LS6 Heads vs. LS1 Heads Worth It?

[99TransAmWS6]

I found a set of used ls6 heads with like 80k on um. Everything on um, springs, valves ect.


Is it worth the effort and probably $500 bucks to swap out my stock ls1 heads? Any major tuneing issues or anything?

[98ultraz]

i would say no unless they are PP and would work well with the cam.... thats just my opioion

stock for stock there won't be much differance. a ported ls6 will flow much more than a ported ls1 though

[DRYSUMP]

buy the ls6 heads and port them

I wouldn't waste your money on them, much better heads out there.

Well $500 here and a couple hundred to have them ported and you are close to a set of aftermarket heads.

If your going to go with used stock heads you may as well buy some used PP heads.
