LS6 heads on 98 engine... What do you have to swap to put LS6 heads on an early LS1, I know the valve covers are different so I am assuming that the valve covers, and coil brackets will need to be changed to the centerbolt version. The PCV is different as well as far as I know so what is the easiest most cost effective way to get a set of heads on this thing? I would like to pick up a set of PRC 2.5 LS6 heads but if I have to change a bunch of stuff to make them work it might make more sense to just have the 241 heads ported...I don't know...

im in the process of doing this swap on a 98 rite now....... and you pretty much have it. i dont think there is anything else other than what you mentioned. if you do the ls6 intake then you need to mess with a couple other things....egr, coolant crossover(i guess you need to bend it?). thats all i can think of off the top of my head.

I will have to keep the ls1 intake because of the egr and lack there of on the ls6 for emissions reasons. I will keep my eye out for some 99 and up valve covers I guess and if I can get some for a good price I will go with that. It seems that people are awfully proud of them though. Thanks for the reply!

i just picked up a set for 75$ are ebay, you'll be able to find some for a decent price you just have to hunt around a bit. im in cali also and i still have the ls1 intake but i will be switching over to the ls6 as soon as i pass smog. after that im going to pick up an ls6 and run it for two years until i have to smog again......if by that time i dont find a ''cool'' smog guy.
You must have a stingy inspection man there, you're about the only person I know modding fbodies in TX that cares to be emissions compliant.

Slp does make a ls6 intake with the egr provisions, I had one on my 98 when I had it. By the way I have some center bolt valve covers I'm trying to get rid of as well, if interested pm me
