Haha....crazy and a sense of humor...I love it. 94formula, thanks a lot for posting that, it's the first time I've seen a 502 and ported heads. And I kind of agree with you. That's been my problem from the beginning. If I could do it all over, I'd do the 224 for sure, but with the 502 already in there and buttoned up, I'm just not sure if the difference will be worth the hassle. UGH!!! Now I'm confused again!

 

Maybe I'll just throw some 1.7 NSAs on there when I slap on the heads and call it a day. You think the CM 612's can handle .561/.569 lift for a decent amount of mileage?

 

See my sig. The 612 is good to .600 lift. I am running a cam with .560/.577 and its working out just fine.
