What grade bolts do I need for the heads on my 59AB engine?

gmc1941 · 07-11-2012, 09:51 PM

Use studs not bolts

Grade 5 will work well.Studs are pia.and not cheap.

Bolts can also be a pita if torqued too much or too many times they can pull threads up and out of the deck. They can also be a pita sealing them in threaded holes going into coolant flow areas. JME

More headbolt food for thought.

Ole Ron should chip in here, but if he does he will tell you that your not building a hemi rocket ship, the 59ab has more head bolts/studs than a modern 500hp engine! therefore a grade 5 bolt x24 is more than enough. studs offer more strength but are a pain, bolts will let you remove the head down the road without hassle.

Thanks to all who replied. I emailed "Hal11" and he sent detailed instructions on welding a washer and then a nut on the broken studs. They both came out fairly easily.

I am also building a 1953 Ford Flathead as we speak and I am using new head studs with the chrome a corn nuts they are not cheap but if you want to build a nice detailed motor you have to pay the price.
