Need good budget LS1 Heads...
I am looking to buy some heads for my Ls1 I am on a budget and want to know what are the best available assembled heads for my $. Also if I go with 5.3 ltr heads how much top end speed will I sacrifice? Please chime in and tell me what you think. Also could someone please clear up for me the difference in the 241 heads and the 806 heads? I see lots of 806 heads for sale but I do not know what they are. Thanks for the input guys.

241s like txh0tb0i972 said, and 806heads are perimeter bolt vs the 241 heads being center bolt. If you want to pay a bit more, 243s flow a bit better and have a ton of potential. If you can find 799 heads for cheap, go for those too because to my knowledge, they are identical to 243s.

Ahh gotcha, well on a budget I'm not sure about which aftermarket heads are cheap. I still do suggest 243's with some porting. They'll flow damn good once you get em CNC'd for what they are.

I thought you couldn't put LS3 heads on an LS1 because they only fit motor's with a 4" bore? Aside from that I agree because I have heard that they flow great.

Hah I don't blame you, there are so many interchangeable parts I'd probably get em mixed up too. How much better are the LS3 heads than the stock LQ9 heads? The LQ9 has 317 heads correct?

I made 468/418 with ported/milled 243s on my old H/C/I setup. Good budget head. There are 5.3s as well. After that you get into the more expensive aftermarket casting heads. You should state what your meaning of "budget" is, it's a relative term, and one man's budget is different from another.

I am going to go with the 5.3 ltr heads, even better for my budget is my brother has a set of them coming off his 2004 GTO in about a week so I will get them super cheap. Now it is off to the cam selection woooohoooo.
