compression ratio and cam combo

[buick83-T]

With the 83 ttype block 290 casting running rjc head gasket kit and .030 off heads what should my compression ratio be at? From what seen looks like right at 9:1...this correct? Running 204/214 cam with this combo have any issues? This is with stock .30 over turbo pistons and 8445 heads.

Well the RJC gasket is the same as the original one so all you'd be doing is shaving the head. If I remember right .030 off would give you right around a 42 cc chamber so you should be ok with the compression but I'm not sure if you'll have enough valve clearence.
