Do you run the 440 source aluminum heads with the gold crane roller rockers? What push rod do you run? Thanks

I did. I used 3/8 pushrods because that's what I already had. They used to take a bunch of grinding with a burr to clear 3/8. I'd go with a custom 5/16 pushrods if you have to order anyway.

Not Crane gold but Crane ductile iron and Stealths. I measured with an adjustable pushrod and ordered thick wall 5/16 Manton's for clearance.

Get thick wall 5/16 pushrods from Manton or Smith Bros and save yourself alot of work grinding.

Stealth heads with Harlan Sharpe 1.6:1 rockers, about 0.600" lift with Hydraulic Roller cam.
Using Smith Brothers 5/16" diameter by 0.083" wall thickness pushrods.

What type of cam are you going to use.....hyd., flat tappet or roller?

I run Mopar performance Part Number P4529560. I run a .590 solid cam with the crane golds. Did have to grind clearance for them though.

After spending a lot of time and money fiddling around with Crane 1.5 Irons, 1.6 Irons, then regular 1.6 Harland Sharps on my 383/451's Stealth Heads, I found that the 1.6 Harland Sharps for Edelbrock heads (S70016KE) were the only ones that gave me correct valve tip geometry without any special shaft adapters, shims, or other high dollar geometry "fixes".. Once that was set, I ordered a set of Mantons at correct length and I was good to go. Nice narrow tip pattern in middle of valve stem with about .560 net lift. Also increased pushrod clearance a ton when compared to Irons. Shanon's hooked me up. They're not cheap but I wasted 2x the time and money screwing around with the other setups.
