I think the L92 head comes as a 69cc how much would you have to mill them to get them down to a LS2 cylinder head cc on factory LS2 pistons and head gaskets? Thanks for your help.

 

i beleive .030 off and a .040 gassket wil lput you close

 

.030? A good bit.

 

I wonder what the ~.040 it takes to get to ~60cc will do to the intake fit? I can be an issue on LS1/6s and FAST intakes bottoming out and mismatching ports.

 

I thought that 1cc = .006 milled off.

The complete L76 intake was delivered today and I should have my L92 heads this week and was planning on .036 from the heads and a .040 gasket. This should give me 11.125 (approx) on a 402.

With the pistons .010 above the block and the .040 gaskets I hope to have a good quench area. Until I get the final cam specs I can't determine the DCR but it should be around 8.4.

All I need to do is get through the next week (hunting) and then I can start the engine swap.
