If they cut the top down, we'll lose dish which will change the CR.QUOTE]
But that would up the compression just a bit, since you lost some of your 11:1 when the combustion chambers grew from 51cc to 53cc.

Yes you are correct. But he's going to put a good mill on the heads so we may lose some of that. 11:1 CR is max here. This is going to be an iron headed pump gas motor. If it's a little less than 11:1, that will be ok. More than that and I may start saying goodbye to pump gas.
