Compression question

[sledder88]

I have a 701 with a speedwerx girdled head with 36cc domes in it. Can anyone tell me what kind of compression i should be seeing with this set up? Im getting 145psi out of each cylinder and wondering if thats low. Im at an altitude of about 700ft above sea level.

That's right about where it should be. Taking into account that not all guages are the same, as long as you have equal compression on each cylinder (within 10%) your engine is likely fine.

ive got a ported setup with 36cc rinning 150 psi, so that's pretty close
