    please help ls2 heads on an ls1

    OK here is what I've got a question about. i have a 100% stock 00 SS. my buddy has a 07 vet, he just swapped heads, and told me he thinks that his old heads (200miles on then comp. DB springs and pushrods) will be a great upgrade for my car. but this guy has more money then knowledge. and i don't know if he even knows what he is talking about. any info will be very helpful i can get the heads for $550.00 and the springs he just put in there were like $360.00. what I'm trying to do guys is get a 400 rwhp car for the least amount of money any help would be great thanks guys. or should i just stay with my stock heads? b/c in going to do cam headers and ls6 intake eather way

    since your buddy has more money then brains tell him to cut you a deal on the heads maybe you can get them for less and that way you save money for a cam, long tubes, cutout, tune, and lid

    how much of a power increase would you see/feel with 243 heads from 806 heads?

    i was under the impression that they will lower your compression ratio that is why people use them to get a couple more pounds of boost from a forced induction setup but i do not know if you will get a gain or not from them.

    they flow better than the other previous heads. you will not see much of a gain with just a head swap. if you have an ls6 manifold, lts, stall (if its an a4), and a cam that compliments the heads you will pick up some nice power. if you get the heads ported and all of the above, you would be over 400 hp.
