Increasing compression - Milling?

[briansjacobs]

sorry I am a little late, but milling the head for compression is less than ideal as it removes contact area for the head gasket. I suggest upgrading the head gasket/studs and make sure your timing is spot on through all RPMS.

My race car had a milled head for compression and the timing was off, we went through 3 head gaskets before we found the problem with timing in the chip.

Looks good, but I cannot comment to the orginal question

Combustion chamber milled for piston clearance

I am just a beginner. Hope it works

[Chuckcruzin1986]

OK, here goes. First step done

You've posted this question twice, with no definitive answers. That is probably because no one has tried this before. Try it and tell us how it works out.

.050" milled. Next step is to cut the combustion chamber edge so the pistons will not contact the head.

if you mil the head, your going to need a adjustable cam sprocket. just fyi.

Can I mill the head .050" without a problem (I will check valve clearance with clay and mill proper clearance)? I am using Super eta pistons in a 2.7 block which are 8.5 - 1 to start. I want to end up with 10-1

I will also mill the outter edge of the piston so to leave .035" to clear the head when the piston is at top dead center.

ideas??
