edelbrock heads with heasd studs and erson rockers
 

is there an issue when running head studs on the edelbrock fe heads with the erson rockers?, if so what is the fix pictures would be great. do you cut the head studs or mill the rockers?.

an issue with height? oiling?

Wrench there shouldn't be any issues. In fact I think you'd have a hard time using bolts any time with these heads. When I threaded a bolt into a couple of holes beside the ex. ports there wasn't enough room for a socket to be used. Look right there beside the #6 ex. port, if not for the small diameter 12 point nut I don't think I'd have been able to torque it. These are from ARP.

Hope that helps, Steve;)

Yep - there is an issue. The stud sticks up far enough - sometimes - to hit the Erson rocker stand. Quickest fix is to mark the contact with a light install (no pushrods) and tap - and then mill (or grind) a clearance dimple/divot into the rocker stand. Takes only a few minutes and wont hurt a thing.

Use the tall valve covers
 

wrench87 I have shelby heads but had the same problem with alignment and clearance. Little grinding and a rubber mallet fixed that. My heads have special studs and nuts from a shelby block and the end stands needed to be modified for clearance of the head nuts. The stock valve covers are real tight. I have the cobrajet stock covers and they could rub in the back corners if a hadn't glued 2 thick cork gaskets together for clearance. I ended up going with the tall Leman valve cover and have no clearance issues. Lovehammer is right about needing 12 point nuts to get the nuts to not hit rockers. I gound down the washers for clearance to the mounts. Washer looks like this []. Works fine. I used ARP studs for my mounting hardware. If you are going to limit the oil going to the heads, nothing smaller than .080" oriface for good oiling. If you are going with a hydro camshaft and run hydro lifters that pump oil through them, get a set of Smith hollow pushrods. The oiling will help keep cool the contact point between the pushrod ball and the cup of the adjuster on the rocker. Run a HV pump and add 1 quart of oil past full. Make sure you get the correct length and ball and cup size for the setup. I think it's a 5/16" ball for the lifter and 3/8" cup for the adjuster. Check on this!!!%/ Good luck Rick L. Ps make sure your oil return are clear of any gasket materials. The Felpro 1246 will cut off some of the return galleys.

thanks barry, that is what i was looking for.

The "ARP/Edelbrock" bolts have small heads and only use a 9/16" socket.
No problems with clearance and they don't interfere with the Erson's.

Ditto on what Barry said, my KC 482 has the studs ground down under the rocker shaft.
