Ported 241 or Stock 243 Im getting heads soon for my ss and i cant decide which ones i should get. Im on a budget right now so I can either get a pair of ported 241 heads or just stock 243 heads, but im not sure because i dont know what goes best with my cam. My mods are in my sig. Any help or advise is appreciated.

If I HAD to choose between those two exactly, ported 241s. But, preferably, I would save to send the 243s off to get ported.

An A.I. CNC ported 241 will make a lot more power than a stock 243, but that's A.I.'s work. Not everybody is created equal in the world of porting.
FWIW, I've picked up 40rwhp on a cam only car with A.I.'s new 241 program. You'll gain 12-18hp with stock 243's.

When I voted for ported 241s, I wasn't voting for some average joe who thinks he knows how to port. I mean quality port work. They will outperform stock 243s. People seem to think ported 241s are worthless.

I am sending my 241s to AI very soon for their HCR219 port. 40-55rwhp is what the claim can be gained. And 450-480rwhp with a 23x - 24x cam. That's pretty impressive for a budget build imo I will keep everyone posted.

Any 241 ported properly will outflow stock 243s. I picked up 51 cfm at peak flow when I had my 241s ported in 2000. MTIs will definately be better than stock 243s.
