12v cyl head poorting
 

Any members out there know of a shop that does cylinder head porting (exhaust, intake match the exhaust manifold and intake manifold also to the head) and valve job while the head is off. Im looking for a shop. or person tahe knows what he is doing. Thanks any help would be great. Todd

not sure where you live but if your near Oregon. I would say,Source Automotive ask for Rip or Bill. I have had good luck with them.

I am in Aurora IL and can do it pm me and I will sent pics of my work Thanks Wiz.

There's loads of places that can do it, but I think it depends on how much you want to spend. Where are you located? Let folks know that and you might get guys like Wizard volunteering their services. :tu:

Cylinder head porting
 

I am open to any conments and sugg. about porting. I live in rochester new york, Has any of you members ported or have ported your 12 valve heads. Is there a noticeable increase in exhaust temp or... Open to conments thanks todd

when I watch my temps after porting they drop some and the turbo pressure comes down a little on my truck I went with 8.3-18 turbo with head port and smoke cleaned up nice its ready for more fuel now.

As Wizard said above, there will be a DECREASE in EGT's. :jump: Porting allows for less restriction. And as restriction of any kind equals heat, and heat is one of our enemies, then it's only going to do good things for your engine. As Wizard also pointed out, if your EGT's come down, you can raise them back up to a safe level by adding more fuel. More fuel = more power = more FUN! :tu:

I strongly urge one to shop around for a head-guy that's familiar with the 12v. Must have a flow bench to ensure actual gains and uniformity across all six cylinders.

- If you're not gonna cut off the intake manifold (requiring an after-market bolt-on intake log ~ $$), then you're pretty-much stuck with cleaning up the intake bowls.
- You can get to all the exhaust ports.

Remember: flow of as much volume as possible is the goal, uniformly, not just hogged out 'n polished pipes. :pca1:
