head studs
I bought a new 6.0 head I been reading that you should have grade 8 studs and nuts
cause of the stock ones will not hold up to the higher compression cause they stretch out and don't keep there torque |

Re: head studs
Try ARP studs.

Re: head studs
I bought mine from Snyder's they were the correct length, there's one just a little longer that's for the distributor wire clamp.

Re: head studs
Snyder's installation instructions suggest 55 ftlbs of torque for both their 5.5 and 6.0 heads. I have been torqueing to this amount for the engines I send out of my shop and have not been having any problems with any gaskets. JMO: You do not need chrome moly studs and nuts to hold torque at 55 ftlbs.
Good Day! |

On a number of engines I've been using Chevy main bolts. They really look nice and they are suppose to hold more clamping load. They are the right length and my dad has built hundreds of engines with them. |

Re: head studs
ARP are the best, grade 8 are next but standard grade 5 are all that is needed. These can be bought at any good hardware store, or Snyders.

Re: head studs
6.0 is NOT MUCH compression! Chiefs' NEW '49 Plymouth had 7.0 to 1 compression. Main thing is to RE-TORQUE the head nuts SEVERAL TIMES!

Re: head studs
Chevy's 365 HP 327 had 11/1 compression with standard (grade 5) head bolts. I think you're OK with standard on a 6/1 motor.

Re: head studs
For 16.00 for chrome Molly over stock studs are worth it to me just to be on the safety side

Re: head studs
As Said
"For 16.00 for chrome Molly over stock studs are worth it to me just to be on the safety side" Or any other head specific bolt from a quality vendor. I would use new studs over 80+ yr old ones, not because they would be defective, but why take a chance. ARP is top quality for a price if you want to spend the extra money they will work fine. I use ARP bolts on any H-iPo builds I do, but bit of an over kill for a 6.0 model A head. The most important part is torque and re-torquing them. After all you are not building a nitro fueled supercharged monster... |
