36cc Heads on a 1300 Conversion
What would the cranking compression be for a 36cc head on a Lowell Horning ported, 1200R converted to a ported 1300.
I was looking at some heads on R&D's site. 36cc sounds a little tight for pump gas.

Hey Spud, have you been able to do any more testing on the 1200R?

Spud,i have special cut 38cc domes on my triple BB @ 4100' elevation,getting 150psi.Im guessing a 36cc dome would give you about 180-200lbs.

Thats what I was thinking Woody. I don't want to go over 150. R&D has the heads listed right on their website. I am leaning towards the 3 piece heads so I can control the water better.
I havent taken the ski back out. I did get a new grate from Carl and the ski is ready to go. I might get out sometime between now and New Years. We are starting up production for parts on the new Boeing 787 and I am really busy. I will end up working most of the break. I also promised a friend that just bought a quad that I would go out to Glamis with him.
I have been purchasing a lot of parts for the GPR though.

Thanks, I tried to call Lowell a little while ago.

Did you spin the dome to 84mm too? That would be an issue.

I was looking at the wrong heads. The 1300 heads are 45cc
