I have to say I think this is idea is just absolutely insane to think a company like TFS would do something like that. They didnt become TFS by pulling shady crap like that. Besides the heads were purchased bare and TFS didnt even know what parts were in the heads untill they showed up there.

They have already stated they found a problem with the rocker studs. I agree and dont see how they would cause the problem but to say that TFS is out there swaping heads on customers whitout their knowledge is just insane....

 

Can you please enlighten us on how we "fixed" the heads.

 

TFS did their share of troubleshooting in the situation....LE verified that with his post. The whole conspiracy theory is just plain BS in my opinion.

So let's examine the differences that could be occuring.
Block...not a possibility per most. I agree.

Headstuds...as I see in the one pic are the only difference that Speed Inc would see when bolting it to your block that TFS and LE didn't have to contend with.

Are the Rockers sitting on the studs for some reason?

 

LOL - TFS conspiracy theory's

Whatever the situation that caused Speed Inc. to see the rollers sitting at an angle compared to the valve stem, is not apparent to both TFS and Lloyd, so it's the only logical assumption that there was some assembly error or bind that was encountered that is now not showing it'self. There is no way that TFS could have corrected the issue had it been rocker pads/holes mis-machined or angle drilled guide holes without significant welding and re-machining or angle boring with larger OD guides...Lloyd would have seen this if it happened, and I am sure that if TFS found something that was their fault they would have stepped up and acknowleged this then corrected the situation.


Stick the heads on the motor and have fun.

 

I feel like we said the same thing here...you just said it better.

 

Gents,
Initially we are questioned on the quality of our product. We quantify the cylinder heads have no defects. Now our integrity is being questioned?

This is flat out ridiculous.

"Just what I was thinking. You dont think TFS would do a switcheroo do ya? Lol. Hey Lloyd, do those heads look like they are from your handywork?..."

"...Maby tfs did pull a switch on ya."

We inspected the heads not once, but twice. We spent quite a bit of time on them, we went over them with a fine tooth comb & we come to the same conclusion each time.

We then send them to an independent third party of Randy's choice, He comes to the same conclusion as us, And now we are accused of switching out the heads?

Unbelievable. Let me guess, The next accusation will be we "bought off" Lloyd so as to not lose face?...

The simple fact is this: The heads were never defective, period.

 

MY THOUGHTS EXACTLY!!!!!


dont sweat it Artie, you guys proved beyond a reasonable doubt that the heads are not at fault. This is the internet, you will always get 1 or 2 who belive in a conspiracy. You have people here who have already backed you up but your just never going to win them all over.

I bought a set of TFS heads in the middle of all of this and havent doubted your product once.

Now I do have one question.. what about an intake to go with those big port jobs?

 

How is it still a question? Because until Speed Inc. says that they incorrectly put together an engine that they have assembled countless times, something isnt right.

That or something is wrong with the block, which nobody beleives is an option worth looking into. Thats the only variable here.

So which is it? Something is different with the heads, or Speed Inc. cant assemble an LT1?

And secondly.....these heads need to be resurfaced? Why? Who in these big companies is not packaging these high dollar heads right?

 

yep, same heads that were ported by me and no modifications done to them (welding, remachining ,etc), LOL.

They worked fine when rolling them over on a stock short block with stock lifters and cam.

The ONLY THING I can see would be the cam/lifters Randy is using (small base circle and possibly lifter plunger sitting in a different location from mine) might be causing the PR to sit at a different location and maybe the PR is hitting the small tube the PR travels through and causing some binding. I believe this was checked already but it is all I can think of as to why the rocker would not sit flat.

???????????????????????

Lloyd

 

As a follower of this "PUBLIC" thread here is my two cents. All the parties involved stepped up to the plate to resolve the issue. A lot of extra time and money was spent to resolve the issue by all the parties involved and in good faith. IMHO the innuendo's in this thread are totally uncalled for.

 

Ehh, really at this point it can only be two things. The Block, which isnt totally out of the question, or the pushrod deflecting in the pushrod tube ( Or whatever technical name, this little pathway is called ?

The only way it oculd be a block though is if it was drastically warped on the head to block surface. Bolting down ALUMINUM heads could somehow possibly make them deflect? But I dont see how any competant shop could not notice the surface being out ...

I say blame it on that bump stick and pushrods.

 

so this ever get resolved at speed inc? apparently trying the heads on different blocks and cams/pushrods causes no installation error. Could the lifter holes not be aligned properly causing the PR's to deflect and move the rockers? I'm not an engine builder by any means but if the heads are mocked up on 3 blocks, and 2 of them check out fine....then the block/cam/whatever at speed inc must be suspect.

 

Ok guys the accusations that TFS did a swap etc is rediculous. I was told numerous times by every source I talked to that it could not be the block. It is not a small base circle cam and I am sure Lloyd could verify since I got it from him. It was one of the all billet cams though and required a bronze oil pump drive gear which I do not really like but Brett said it would be ok so its installed. I really hope everyone doesn't start changing their mind about it being a possible block issue....

 

well if the heads are fine and 2 people said so and the block "can't" be the issue then bolt it up and call it a day and run it.

 

there is obviously some issue at Speed inc. Its either an assembly error or some sort of vale train binding issue with you particular set up. At this point I would have to belive Speed inc will start looking for the cause of the binding when they get the heads back. I dont belive they are at fault with assembly, but they may have overlooked some issue that obviously is not an easy find.
