Stock heads?
I noticed that my had has them when I bought it a few months back and I'm wondering if I'll see much of a gain in going to aftermarket ones, or should I spend the money else where?
But to answer the question. No 243 heads were not stock on LS1 F-bodies. That is the LS6 head.
The 01 & 02 F-bodies had 241 casting numbers.
Maybe I should take another peek just to double check that number.
Is there any way to check its a run of the mill ls6 head (presuming I did readit correctly) or an aftermaerket unit?
IE: other casting numbers, model numbers, ect...
