Head Difference 80-82
Is there any performance difference between a 80 L-82 stock head and a 82 L-83 stock head? I know the L-82 has threaded rocker studs and pushrod guides where as the L-83 dosen't. Other than that is there any difference??

Re: Head Difference 80-82 (82zoom)
Thanks Jim but I too have a set of 80 L-82 heads sitting in the garage. I'm in the process of changing intakes on the 82 and thought well if I'm this far why not have the 80 heads cleaned and tuned up and stick em on the 82.

same heads, maybe the L-82 has the la4rger 2,02 & 1,6 valves, the 82 has 1,96 & 1,5.
I was told long ago that the last 2.02"I/1.60"E-valved head was the '72 LT-1, but I can't confirm THAT, either...
Marck, I was under the impression our '82s had 1.94"I/1.50"E valves, not 1.96"I. Was that a 'typo', or am I wrong (again???)?

Re: Head Difference 80-82 (Glensgages)
that was a typo :)
The 462624 head is still offered by GMPP as the hi po (ahum) iron head, it has 2,02 / 1,6 valves and screw in studs, maybe the L82 has the same but I think they''re all the same.
