As long as your rocker studs are 3/8" and you have enough valve cover clearance they are a direct swap.
I was doing some research yesterday and seen that, to be honest I’m not 100% sure I didn’t look at that when I had the valve covers off but I think it’s the stock style push in, I’m going off this picture and it doesn’t look like it’s a after market threaded stud as it would have the nut under the rocker right? Zoom in on the number 3 exhaust rocker
Seen mixed reviews on using the stock stud with after market rockers some said do it some said don’t and if I do want to tap it I would have to take the heads off huh
yeah it's always a crap shoot.you could rock the full rollers and be ok or....not.if you were to go the screw in stud route it's an all or nothing situation pull them off and it becomes less than cost effictive..those are the pressed in one's,you're rite there'd be a hex shaped under the rocker arm. roll the dice,let us know what happen😉
