I am thinking of porting my intake manifold. Now if I ported and polished my heads too would that make a big difference?? If not what else should I do???

 

Depends on who does them.

Do it yourself, probly not, but another company yes.

Good Luck.

I think heads are one of the largest restrictions on the LT1. Therefore, you should definitely get them done and do them right.

 

I did mine myself, took about 10 hours. I haven't been able to get any results yet.

Shhhhhh....

Actually it's boredom, and I like to tear stuff apart that I have no need for. Also I do what most people talk about so it gives you guys some ideas and help.
And makes me faster for cheap..

 

I wish I had some experience to do this stuff myself ...and tools

 

I got a Stanley set that cost $70. I threw in a couple of other Tools, and I got everything I need to tear it apart.

 

It's not easy, but helpfull. Just read up on it and save yourself a boatload by sending it in. Summit and Jegs have bit kits for it. My friend uses mill parts and modifies their shafts to fit in the dremel. Cuts through metal or aluminum like crazy. Of corse, get the alu bits, so they don't clog up. Remember to at least port match the intake so there's no edge the air smashes into when it goes into the heads. When you port match, use the gaskets you plan to use, and just take a marker and mark the inside of the gasket, then dremel out to that line. No more or else you'll just create another airflow restriction with the gasket. The polishing is what will make a bit more gain. The inside of the intakes aren't smooth, which creates turbulant air and robs HP. The smoother the airflow, the better. Hence mandrel bent exhaust curves, not cheap rippled ones.

 

Pretty much what I did..
