			Time to CC the set up and adjust the deck height for the target CR.  It is fun...........   Cheers

			I shoot for no more than .040" (.1mm) per Steve Wiener's recommendation of .035-.040". I've measured higher on a stock 964 motor but your SC measurements seem kinda high. Have you decked the case spigots yet? -Chris

			You still don't know what the CR wil be if all you have is the head volume. You might want to measure the piston dome voume as well.  Cheers

 henry had spec'd these out as 8-1 CR with stock sc heads(The Je pistons almost are flat with very little dome and valve releifs cut in them already) which is pretty much what I have nothing was machined on the heads other then chamfering and the twin plugging I should restate I measured the 78 sc engine my garage(stock motor) and that measured considerably higher then mine..

			If you have the case apart you can have a local machinist "clean up" the spigot sealing surface. This will give you a nice "true" foundation for the cylinder+head+cam carrier stack and get you a better deck height as a bonus. How are you measuring your deck height? -Chris

			dial cailper in 3 spots 120 degrees apart. Case is together now. I have read a bunch on this and allot of folks are suggesting that 1.2-1.3 mm is good to go for a turbo engine what do you think?
