that to me seems on the low side for stock.... My stock heads were around 120-125.... You have some base gaskets going? How many miles on the top end? Rebuild time possibly

I your not using a small engine comp gauge you may be getting a false reading.

hmmm i tore it down last year to inspect, so gaskets should be good.... its been two years on rebuild.

and yea i am using a cheap princes auto automotive tester...hmmm

also when i tore down last year, i was right on the limit on piston to cyl clearance so i might just rebuild this year..... don't wanna take any chances...
