Well depends on what you want to do with the car and how much you want to spend on a 346 cubic inch motor. To be brutally honest its hard to beat a set of ported 241 heads that are already on your car with just simple work because you already have them and plastic intakes are restrictive.

Do what? Where did the OP mention he already had 241'a because I defiantly missed it in his post. And how are plastic intakes restrictive? Do you have any idea what your talking about?

OP, sorry I can't directly help you from experience but if your running a stock bottom end, a set of nicely worked 243's will pair up nicely. If you already have an ls6 intake I would just save the money and keep it. If you wanted to go big or go home, a F.A.S.T. 92 will sit nice on top as well, but since it's a plastic/composite I wouldn't buy it because they don't flow well... good luck.

OP: With a smaller cam like that a stock set of 243's will work nice since they are a good upgrade over stock ls1 heads and its cheap HP without having to break the bank on porting and polishing etc. that is if money is an issue....

Plastic intakes have a 90 degree bend before the cyl. head ports, and all the air comes in on one end so some cylinders don't get quite as much air as others, that's how they are restrictive..... but any FAST 90/92 will work great for what the OP is trying to do.

Plastic intakes flow less than great heads at upper valve lift levels.

If you have a a large cam, pick the best heads you can afford.

If you have a modest cam, pick the best heads you can afford.

Pretty much what I said, he has a small cam so the upper valve lift isn't a factor and stock 243's are fine....

Unported it is a waste of time. Send your LS1 heads to AI and get their 219cc cnc program.

Nice thanks for all the feed back guys! Well I've seen 243's on the for sale section go for pretty cheap about 500 so thats not to bad and I know thats what alot of people use but I just wasn't sure if it would be worth doing any thing to my 241's or just get some 243's

Done by the right people 241s will come within 20rwhp of a ported 243. So your 241s ported by AI can be worth up to 40rwhp.

No such thing as easy Hp. We usually like power we can feel. That requires attention to details, patience and $$$.

There is if you know what your doing....

OP: You also can take 243's and have them milled for cheap and will give you a bit more compression and will make more power with the cam you have.
