[adk-roadrunner]

Hey guys I'm getting ready to order my valve train parts for build. I am having my stock 452's refurbished while retaining stock valves but need to know if the stock valves are 2 or 4 groove for the keepers. The heads are at the machine shop he's not there and he doesn't use email and I want to order now I thought he told me 2 groove but can't remember. Thanks guys

I may have already figured it out but need assurance is it 2 groove and 4 groove .4 groove for intake and 2groove for exhaust.
