[1939 Pontiac Silver streak head tightening sequence]

Done. Thanks again. See if I can get it out to get it up to normal running temp and retighten the head to spec.

The old beast (original flat 6) did 560 miles (just over 900 kms) in 2 days to drive it home from South Australia to Victoria here in Australia. No problems.

Thanks for your reply Bloo. I’ve only just bought the Pontiac and want to try do things the right way. I think 60 FT/LB is correct and the same for both the 6 and 8, it’s the tightening pattern that I can’t find out about, I’ve searched the net high and low to no avail. Not a major problem, I’ll get there.

Hi guys it’s my first post here, and I’m inquiring about about the torque specs and tightening sequence on the head of my Pontiac Silver Streak inline six 223ci. Any help would be greatly appreciated. Thank you.
