Hey guys would putting LS2 heads on an LS1 help you gain power? also how do I know LS2 casting numbers and how difficult are LS2 heads to acquire?


Thanks Guys Anthony.

Yes, they will fit. Yes, they will make more power. Casting number will be 243. They are for sale on here all the time..

Casting #'s.


Very good stock heads. C5Z and LS2 heads. if you want, get them ported or do an exchange service for a set of ported ones. Just search for 243 heads for sale. Ported they go for around $600 a set with stock springs (yellow.)

Thanks guys, I dont have my motor yet but hopefully I can get some decent heads for the right price and get them worked and ported. Put those on an ls with a new cm and intake hopefully will wake things up.

Are 243 heads hard to find?

no, there are probably a few sets on here for sale now. You can also look for 799's. They are the same casting without the sodium filled valves.

Also, 799's castings are LS2 heads as well. They are the same as the 243's without the hollow stem valves.

Not all 243's have hollow and sodium valves.

Ok I am gonna be on the look out for a pair, I am gonna try to get an ly6 motor but if it looks like theyre going to cost to much I will stick with an ls1. I have one Im going to look at tomorrow its a 02 ls1 from a ws6 trans am with 60k on it, he wants 2500. Im going to try and talk him down to 2000. It comes with harness and auto trans. even has an ls6 intake.
