I just had the phase 2 of the wrench report done to my tri-z cylinder and head. I gave the guy a crappy head to do cause I wanted to see how it would come out before I use a good head. Well he said that cause there was so much pitting in the head he cut it 1 full MM as opposed to the
.76 MM the wrench report calls for. He reshaped the dome and squish band and made it beautiful. He said that it has a 20cc dome and will probally have 11.5 to 12:1 compression. I don't know what kinda cranking psi it will have. Can that be right though? Does a 20cc head raise the compression to 12:1 even with the exhaust port raised 2 MM? Does anybody else know what compression the phase 2 of the wrench report brings the tri-z at when it is done excatly as said. I would really appreciate any help. Also here are some pictures of the head. The reflection and the way I am holding it make the squish band look uneven but believe me it is dead even. Thanks Denn

sorry guys, how do you add pictures. I clicked on add an attachment and got the file name and hit add attachment but nothing came up. Do I have to put something in the file comment section. Thanks Denn

I believe the compression with a stock( flat top) type piston is in the 10.5:1 range with .76 milled off. I think your mechanic is in the ballpark . let us know how it runs.

Ok guys I know this is a little off topic but Im thinking of taking my T3 head and having .76mm milled off of it. If I did think what kind of ratio should I run and what kind of octane gas? Would Amsoil Dominator Series 2000 mixed at 40:1 with 1/2 premium 1/2 race gas work?
