not CNC'ed
hand ported and 3 or 5 angled. Claimed that the bowl has had alot of work and .010 decked and beehive springs. I am worried that the handporting even though it was professionally done, is not worth it.

I have my heads that are 3 angled and .007 decked polished more than ported (I did it) mainly in the port openings. not gasket matched. 918s and new valve guides. I think my material removal was more on the exhaust ports and the intake ski slope.

pictures of "new heads"

 

No way to truly tell without getting them on a flowbench.

Also it would help if you took some higher resolution pictures - those pics don't really cut it.

 

Doesn't look like they touched the valve guide area and the guy stopped the cutter a lot at the bottom corner of the ports.

 

I was wondering about them because of the "no valve guide work" thought there was alot to be had there. Those are the pics I have to work with, I will email the seller.

Those are hacked up home-ported heads. Not worth any amount of money.

 

lmao Those heads look pretty bad. I will stick to letting professionals deal with heads. Not worth it if you hack them up, and a professionally ported set of heads hold a decent value.

 

I read up a lot on porting heads, then got the standard abrasives porting kit and went at it. Farking 80 hours later, they were ported. Who in the hell knows what they would flow and each port probably flowed something different. The car seemed to run 'well' but no way I could say they I helped or hurt the performance. The car went 11.8 with a 100 shot in a full street weight, street legal car using the stock 3.42 differential and a six speed. In N/A mode, it went 12.8 with the LT4 Hot cam kit.

Bottom line, I would only recommend home porting to prisoners convicted of violent crime. It takes forever, you may be doing damage instead of improvement and you can't quantify the symmetry nor the 'improvement' (unless you have a flowbench which most of us don't)

If your time is worth anything per hour, plug the numbers into a spreadsheet and see what I'm talking about.
If you were making 20.00 an hour and spent the 80 hours I spent on mine, you're looking at $,1600.00 for your LABOR alone.
If you make $45 an hour, then $3,600.00 for your labor alone. If you spent $2,300 for some verified, quantified and proven TFS heads from Lloyd Elliot or AI, you're WAY ahead of the game. Work overtime, or save up your money each month, take a second job, etc and just buy the high quality components and know that the knowledge behind them is solid and proven. IMO of course...

 

I haven't seen them in person...but the pics are pretty bad. He claims a porting guy at etheads.com did the hand porting, but they offer cnc porting...

 

Avoid at all costs.

Period.

 

Looks like the valve job was hand blended to the port, and the intake and exhaust were port matched to the gasket...nothing to pay extra for and doesn't count as "ported".

 

A little crude but was thinking the same thing.

 

This. We've home ported a few things over the years and they looked far better than that. Those are hacked up.

Just doesn't look like much was done.

 

Did you ever say how much you paid? $50.00? swap for parts..? Date with the cute girl down the street?

It was NOT professionally done.. I do all my own heads and it looks like they used a non-ferrous metal bit and then NEVER smoothed it out with the sanding rolls.

All you have to do is ask him to finish the job that you paid for..
