460 Roller rocker conversion question
I have a set of c8ve-e heads on a c9ve-b block. I got a new Lunati 61601 cam and lifter kit. My question, what do i need to convert to a set of roller rockers. What is a good combination someone has tried and used. Also what valve spring should i run?
thanks in advance.

On my 460 C9ve I used ARP 100-7101 rocker studs,Comp cams 4838 guide plates,Comp Cams push rods 7934-16 3/8 inch.Howards Cams also has a hardened .080" pushrod for 65.00 through Summit,Comp Cams was 150.00.Springs were matched to my cam,574-554 lift Comp Cams 4x4 extreme grind.Rockers are Crane Cams gold race 1.73-1.Now,some guys on 460 ford.com have said that the rocker stud boss must be milled down equal to the thickness of the guideplate to maintain proper valvetrain geometry.I didn't mill mine and I don't have any problems.I was fortunate enough to be able to use 8.55 in pushrods.You should measure to be certain.Valve springs,retainers and locks should be matched to the cam.You should have specs from Lunati.I don't know the lift of that cam,but you should measure the clearance from the bottom of the retainer to the top of the valveguide taking into account the thickness of the valve seal.You may need to have the guides machined to allow clearance.Harland Sharpe makes a 1.73 ratio rocker for ~ 240.00,1/2 the price of the Crane gold.I am also running stock stamped steel POWER by FORD valve covers.
