Yes they're the 2295 trw's. Going by memory the dome height is .130. But not sure how I would get chamber depth, unless I convert the dome height into cc's, then subtact that from the chamber cc's, then convert the diff to thousands? But wouldn't that tell me volumn, not depth? Hope I made sense. I'm picking up the 915's tomorrow from being cleaned up and surfaced. I guess I could live with whatever quench I could get from this setup. I just want to use the right head gasket for optimum performance. Ballparking the pistons are down about .046 with factory 915 large valve heads. Thanks guys, you're helping quite a bit!
