my lag is your courtesy head start


ATTENTION.... installing a head gasket, head studs or pistons and rods in your otherwise STOCK engine dose not make it a "built" engine! stop listing you cars for sale saying they are built when its not!!

9.6:1 - P74 LS Pistons
10.0:1 - P72 GSR Pistons

and this is if the head isn't milled.

~10.2:1, but you won't be able to rev it very high on stock LS rods (rod bolts).
