it will have more torque then most 02's out there

yes

its a dr Shrick 284 cam and the valves dont show any evidence that they ever touched the pistons and like i said the leak down test was 3% although i wasnt actually able to tell where the 3% went anyway im anal about stuff like this so i ordered a set of ross 89.9mm pistons

Hello peeps! bought a engine from craiglist a few years back. installed in my 76 and ran it with full synthetic 20/50 for about 40 thousand miles then i noticed it started leaking oil from the oil pan and the cylinder head and the timing cover so i yanked it out to do a inspection tear down/reseal now this engine ran real smooth and didnt seem to lack any power. anyway i measured the compression witch was like between 163-170 psi across all 4 cylinders and the leak down was 3%. the thing that irked me was how much carbon was on or in the intake track so i cleaned it all off and found piston to valve contact evidence on all 4 cylinders then i found some really strange paint inside oil gallery fyi the pistons are Arias type anyway take look at the photos and tell me what you think

install a wide band A/F sensor then use the data for tuning and if your still getting the same condition start looking at mechanical issues like valve adjustment. compression, leak down. etc.etc.etc.
