Scatpack, I havent pulled the pistons yet so I dont know that the clearence is down low.

HodRod, yeah I cc'ed them yesterday, and they came in at 62cc's which surprized me. I have another set of J heads with a 2.02 stainless valve and it cc'ed at 68-69cc's. I quess they were milled a decent amount, plus I'm sure the manley valves add to it not nearly as dished as stockers.
