I di the GM performance aluminum heads and the zz502 cam on my MKIV and am pretty happy with the results.I also upped my compression to 10:1which with the 110cc heads makes it about 10.7:1

Can you run regular 89 octane? I am only using the small dome pistons so I am closer to 9-1 compression. I think the 110 heads will get me where I want to be. Where did you get the heads and what did you pay for them if you dont mind me asking.

I have a set of the square port marine aluminum heads. Don't remember the number, but they have a fresh valve job, no springs or retainers. $900 plus shipping for the pair. THey flow about the same actually as the ovals. Use a square gasket with your ovla intake. The edelbrock head is really more for hot rods and stuff. They won't make much past 500 HP without a blower stacked on top of them. I have about 6 dyno pulls on this valve job. Have inconnel valves etc on them.

I run 93 just to be safe.Asfar as price,I did some horse trading with the owner of a marine engine company. You can order the heads from any GM dealer.Check with some of the board members I amd sure there is someone that works or has ties with GM. Or you could save a few bucks and buy Jeff1000womens:biggrinjester: heads He has some good stuff and can put a nice package 2gether 4 ya.

Pistons and piston pins

Not real familair with that engine but Im guessing a Gen 6. Cam probably doesnt have a fuel pump lobe. Are the heads aluminum ovals?
