Re: Cylinder head problems

Where are you located? I can probably suggest someone to fix them up for you. To someone that works with this stuff everyday, this REALLY is not that big of deal. I certainly though wouldn't replace a nice head, with something that is using 20 year old technology.

not unless you have deep pockets, and don't mind burning them up.

but possibly I don't know the entire story, either way good luck with whatever you decide to do.

Ok here is the whole story, tell me what you think. I had a friend port both of my heads, he isn't a professional by any means but has probably done a dozen sets of heads without incident. He finished my first head, the only problem he ran into was he started a pinhole on the roof of an intake port into the spring pocket- no big deal I can have my machinist epoxy it.

The second cylinder head he noticed a bubble between the intake and exhaust port when he finished porting. I took it to my machinist and sure enough, it was a thin spot. We poked it to see and it made a hole. We poked the other 3 intake/exhaust walls and 2 of the 3 made holes.

So I sent it off to some place in Milwauke, Oregon to be welded. They were supposed to be really good, they told me it was impossible. I took it to a good friend who is a big name speed shop owner/awesome welder and he tigged the thin spots and added material back in.

Minimum they need to be checked out by a machinist, the ports need to be blended back out, the seats need to be checked out and they need a valve job due to the slag. I am scared of putting that kind of money into a head when there is a chance they might tell me it is junk.

What do you think?

Re: Cylinder head problems

Can you take a couple snap shots? I would like to see how bad we are talking.

Just about anything can be fixed, it just takes time.

Where the heads on a flowbench at all? I don't know of a reason to make the bowl that thin.

The last time they were on a flowbench they went like 291 @ .650 and I don't remember what they went on the exhaust. I dunno I don't port heads but I can get pictures. I will take some this weekend and post then up. I appreciate your advice.

you aren't reffering to the track1 cnc head are you. its the best flowing 23* cnc 227cc port around. I have made in excess of 500rwhp with them. 20yrs old or not its a damn good head.

Re: Cylinder head problems

Collins,
That post was not directed at you. Although, I am not a fan of some of the Brodix stuff, the post was made in the general, not the specific.

Re: Cylinder head problems

I like the Weld Tech CNC stuff much better myself... they might not have big flow numbers like the 227's but the CNC work is better and the port is pretty bad ***.

Re: Cylinder head problems

Bret,
Comparing the OE CNC providers, Chapman is probably the nicest, Weldtech second, and Tommy third. Though Tommy is pumping out some serious volume now, so unfortunately the stepover gets cranked up, and the cutter paths are not as refined. Whats that old quantity / quality debate? Have you ever seen tommy's one off stuff?

On a side note (not to hijack the thread) but I had a set of 11RI's in a few weeks back with weldtechs old port in it. I toyed with the VJ and SSR and picked up about 40 CFM This was by far the hottest 11RI head I have seen! Quiet as a church mouse. The moral of the story...when a dirt burner is selling his old weld-tech's for $200.00, buy them, have someone put a couple hours in them, and you will have one fine head for cheap!

Back to the grind

Re: Cylinder head problems

Dennis, I might have to send you my Weld Tech T1's then for a tuneup. I wanna throw cometics and some beehives on that motor with a new stick so a little more compression and some tweaking might help.
