Chevy rockers on eddy heads?

[chargd72]

Is it true that SB Chevy rockers will work with Eddy aluminum heads for SB Mopar?

Not positive. In certain cases the shaft mounted rockers are interchangeable (I know they are on my Magnum aluminum heads). Better wait for someone more knowledgeable.

I would ask Edelbrock, there tech dept. is pretty knowledgeable. I do know that you can not use older rockers on LS-1 engines and LT-1 rockers can be used on l-98's, not not on any other chevy SB. Hope that helps.

Thanks, I'll check with the Eddy guys when I'm ordering heads.  Thought someone on here might have tried it at one time or another.

Small block Edel magnum cylinder heads.   Yes they will.   Assuming 1.6 rocker ratio, clearancing the pushrods to the head is required on older LA style short block with short lifters, as the magnum heads are designed to go with the taller roller lifters.  A little grinding on the pushrod holes was required, not a big deal.   I also ran 1.65 rocker ratio, could probably run 1.7 ratio.
It was easy to get a good roller tip contact pattern on the valve stem tip and have correct valve lift.

Perfect!  Thanks for posting.
