Heads are at shop getting at least one valve guide replaced. One i could wiggle the valve. I quit checking after that and delivered to the local race machine shop.
Prior, I re sealed the intake rocker studs and that helped some.
Compression was 225lbs

when the heads are done i will bolt them on and try it.
it was suggested to me that cheap leakdown testers may or not be reliable... so I didn’t get one

My cheap HF leakdown tester works fine... and they are easy enough to test with soapy water if one suspects they are leaking..
