2 sets 243 heads and two ls2 intakes forsale

[sman]

Correct.

Sman I dunno what size chamber is on a 5.3 head, but a 243 head will smoke a 5.3 head

But it also drops my compression a ton. Im only 9.4 to 1 to begin with, im looking to raise that to ls1 teritory.

JUST found it,

Chamber volumes
5.3 862 heads-61.5cc
Stock 241's-66.67cc
Stock 243's-64.45cc

What version are the CNC'ed GMPP 243's do you have the 60cc or 65cc? Anyone know if the 60cc ones can be milled at all to bump me up a few tenths?
