Skiatook ok
I need a vendor where I can get 3/8 stem valve locks and retainers for my 440. They are stock valves and I can't seem to find them anywhere.
Thanks for any help.
 
Rockauto has them listed. You should be able to get them through most local parts stores.
 
Locks:
Intake 2gv: PC746HD (Pioneer), 121-1000 (SBI), VK66R (Sealed Power)
Exhaust 4gv: PC766HD (Pioneer), 121-1014 (SBI non-hardened), VK174R (Sealed Power)
Comp Cam: 602-16 (2gv), 604-16 (4gv), 606-16 (2gv & 4gv)

Retainers:
Comp Cam: 744-16
EPWi: 03-1005-16
 
Thanks but my locks are 2 and 3 groove all I can find are 3 and 4. But I will check.
Mopar (old skool) only used 2gv and 4gv, while late model stuff will have a 3gv.
 
Ok next question, 906 heads with 3/8 valve guides 7 or 10 degree locks?

Unless you are going over ~0.525" Valve lift, 7 degree locks will be fine. Anything with more lift should have 10 degree locks. Order the Comp Cam stuff from Summit Racing; Locks 606-16, and Retainers 744-16.
