shots from the garage...
for comparative sake the Duster engine has 200-210 lbs of pressure to get the valve off the seat. My W8 360 sitting in the shed has close to 320 lbs off the seat. Think I'd best pull a spring and get some installed height measurements and make dang sure what we are dealing with. At this point, looks like we'll be running high 10's at Bakersfield for March Meet. Iron head 360 coming back into duty.
