i believe the 6.0 uses a .060 and the 5.7's use a .052-.054

Something is not adding up right between the LQ4 and LQ9.

Are the heads differant on them also? I thought the only differance was the pistons.

4.00" bore
3.622" stroke
71.06cc chamber
.060 gasket
4.100" gasket bore
-.008 deck height
-6.6cc piston

9.38:1

OK

I feal stupid the LQ4 has 9.4:1 I thought it had 9.1 and things just were not adding up.

Give the new numbers this is what I have.

4.00" bore
3.622" stroke
61.15cc chamber
.060 gasket
4.100" gasket bore
-.008 deck height
-6.6cc dish

Giveing me a 10.4:1 CR

but I have plenty of room for milling.

Next question is how much can I mill the heads before I have issues with the intake manifold.

I think I can only mil it .030 if so I think that will bring my CR up to 11.3:1

Can I mill it amy more than that?
