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

As Wizard said above, there will be a DECREASE in EGT's. 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!

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.
Intake bowl . . .
Exhaust bowl . . . .
Exhaust port (floor)
Valve un-shrouding . . .
What about O-rings?
How fast do you want to go?
