Perkins 6.354 Head Studs

[RCP]

Where is a good source for head studs for the Perkins 6.354? AGCO wants $100 each for the studs.

Re-use the old studs, they are NOT torque to yield hardware like newer engines use. Or, get them from ARP who makes studs for race engines if you know the length you want. I've never had to replace any studs on any Perkins I've ever worked on, always used the original hardware with no trouble.

I agree with you, but these studs are in bad shape, rusty and the threads are stripped.

I'd use the ARP catalog and get them there, I'm sure they would be less than Agco and better quality too. Not sure if they have any with fine threads both ends like Perkins use though. Might switch to bolts also, that's what some later Perkins engines now use instead of the studs.
