1972 gmc 402
hi
issue is this: 1972 gmc pick up 402 th400.
low compression # 5,7,6 at 25 lbs
pulled valve covers and on rt side 3 rocker arms loose and sideways.
intake pushrods bent. left side #6 same thing
only intake pushrods look bent but will pull all rockers off to check all.
the truck has only run to drive home 6 miles 1-1/2 years ago.
this is a project so wont pull heads now, but know I have to.
any good mechanics out there might have idea?
thanks
