hmmm about that bore size. I have a 3.905 bore with a shaved block with pistons .010 out of the hole and forged pistons with 7cc valve reliefs for 2.055 1.60 valves. 98 heads, o-ringed, with large chambers. what do you think? I am looking for greator compression.

Your quench would be only .017", not much to go there with 2.055 valves even with 7 cc reliefs. What size chambers are your heads? how much milled? These gaskets put me at 11.0 CR with 62cc chambers and I get a .035" quench, which is about perfect for what I want...

I believe by looking at them and not actually measuring them that the chambers are stock cc. save for the new valve seats and larger valves. Heads were one of 3 sets origonally built for a turbo project so I am sure they are large chamber and not less than stock. Heads have only minor clean up and I had o-rings installed. Will these gaskets be compatalbe with o-rings?
I think 98 heads came with 67.67 chambers?
