Has anyone out there ran the combination of the small block Indy Edelbrock heads (with the offset rockers) along with a hydraulic roller cam? I'm having major issues with the clearance for the push rods through the heads. The owner of Indy heads told me he never considered the combination and has no idea if it will work.

The tightest fit is on lower inside portion of the pushrod hole. I don't know if I can even grind off enough aluminun to gain the clearance I need. I don't want to grind the hell out of it and find out it's not going to work anyway. I don't want to get rid of my roller cam if I don't have to. I'm hoping someone else can tell me they've done it and it'll will work.

I have those heads on a 9.350 deck with a solid roller and 3/8 push rods had to do a small amount of work with the die grinder.

I'm also concerned about the extreme angle of the pushrod. Small block Mopars have an extreme angle from the factory and then you add the longer lifter and the offset rockers and it's amplified even more. Is this ok also?

a w2 motor has more angle than these do should be fine

I already ran the engine with the hydraulic roller cam and lifters. I had performer rpm heads and just changed to the Indy Edelbrock heads with the offset rockers and relocated push rod holes. It really looks as if it won't work, but I guess if others have done it it must.

This is how far they are off. The pushrod hole is so far off, the tip of the pushrod can not even seat in the lifter and you can see how far off it is to the rocker.

Did you use these same rockers from Indy? I think I'm missing some spacers between the rockers and the shaft mounting posts. Besides that some of the rollers don't even turn.

I called Comp Cams, they don't make an offset hydraulic roller lifter. I'd hate to have to get rid of these lifters, I paid $700 and they only have about 1000 miles on them.

What is the offset on the intake rocker arm. I know the Indybrocks require a different intake rocker arm but the offset on yours look the same (intake and exhaust). Probably just my old eyes.
