Does anyone know the type of clearance required with Jesel shaft rockers? Should the old valve covers that worked with the Crane Gold rockers fit (they did have the outer corners rounded off)? They are the black finned covers that you commonly see with "MT" or "Holley" in a recessed area. Thanks,

Get a set of aftermarked marine valve covers. I use the EMI, many others make a similar product. I have the breather stacks to reduce back pressure. Only downside is I have to run the blower all the time to blow out the oil vapers.

I can sell u mine,,B&M 2 piece ,,,1 set only.
But i have the jesel shaft stuff in there. The stock finned ones will not clear.

The 2 piece KE are good as well and fit.
