P&p

[RadRacer]

Have any of you ported your own heads? My dad is going to be doing the heads on the LT1, and he said if I could find a spare set I could try out porting them on my 97 Camaro. Any suggestions/recommendations besides let a Pro do it? One of my friends is a race shop owner. I'm going to ask him about it and possibly have him "supervise" that way I'll know I do it right and still be able to say that I did it myself. Do you think I should also get the upper and lower intake manifolds and give them ago? How much should I be able to port, on both the intakes and the heads?

Re: P&p

never a good idea to home port heads. easy way to screw up flow and cause valves to seal incorrectly.

know thats not what you're looking for, but its the truth.

I know. I've done my reading and research and mainly just wanted to see if anyone on here had done their own. Main reason why the car's even possibly going on the lift is because of a slight coolant leak I have at the rear main. Figured, if I have to tear it apart to replace that, why not do some upgrading while I'm at it? I'll check with my buddy to see if he has any suggestions on porting them, or even doing them for me. In the meantime, anyone here done their own P&P to the heads, UIM, LIM, or even the TB? I know TB isn't a good idea, but just figured I'd ask.

Re: P&p

Yeah I have ported my heads and intakes. I assume you looking to do it on the 3.8L.

The best thing to do for the top UIM is to gasket match it to the LIM since there is not much metal to play with. On the UIM you mainly can smooth out the port sides and take some casting excess where the port is extruded into the upper plentum.

The LIM can be matched to the UIM, then the sides of the port can be expanded since the sides come in a little. The LIM port can be matched to the cylinder heads to keep the flow uniform.

Are you going to port the cylinder heads as well? That is where if you have never done porting you should be supervised.

I have heard that porting the throttle body is not worth it since the flow capability is there and you will not run into problems unless you are running a pretty sick set up to max out the TB.

My car domain site has some pictures of me porting the upper and lower intakes. Forgot to take more pics of porting the cylinder heads and adding the ls1 valves. http://www.cardomain.com/ride/804031/1
