QUOTE(OU8AVW @ Dec 12 2013, 03:56 PM)  Anyone wish to chime in on the minimum deck height on these motors? I'm seeing .030-.045 as the minimum. I believe I went with .035" deck height on my build ...... if that wasn't it, then it was .040" ......... what ever the number was, I recall calculating 8.4:1 static compression ratio at that time, my pistons also had a valve relief that I think was 3 cc of volume .....

I see were you're getting the extra 2.5cc
  If you shimmed the base so the piston aligned flat with the top of the barrel, wouldn't the deck height subtract the area you filled to the brim? |

I did mine the same as Stu. The disk is flat across the chamber recess like the cylinder is. I sealed it with grease. I think my heads just have had less machine work done over time than others.
I'll PM Jake and report back. |

I didn't realize you had a plate in there. Hard to tell at first glance, but I see it now.
