I've got my head ready to go to the machine shop, if only I knew how much to mill.
the chambers came out at 59.2 to 59.8 cc, and it looks like I want to get to 52 cc to achieve a 9:1 compression ratio. That assumes a 0.050 head gasket thickness and 7 cc dishes in the pistons, which I'll verify when I get home tonight.
If that assumption is correct, then how does a reduction of 8 cc translate to thousandths of an inch milled from said head? It's a D8BE head casting number. I can see the impression of the head gasket part no. D7BE printed backwards on the head, so I assume that this head hadn't been worked on prior to my getting ahold of it.
My goal here is to be able to use regular gas in this thing. If I'm pushing my luck at 9:1, please let me know!
Thanks!
