Guys, I got the 383 together, I'm using some edelbrock 6085 heads with .100+ taller manley valves and k-motion springs, But the delima is that I need taller rocker studs but nobody makes them in centerbolt(3/8) in the size I need. My only options are to either put a spacer on the bottom of the stud which will leave less threads in the head, have the rockers machined the extra .030 on each side and fit 7/16 rocker studs in, or put 7/16 studs in and 7/16 roller rockers in and then modify my valve covers to work with the wider rockers.

Has anybody ever had this problem? If so I would appriciate and suggestions and advice.

Thanks,
Brendan

 

Why taller studs? That's almost never an issue... usually they're already too tall, if anything.

 

From what I can tell, there is about 4-5 threads showing through the rocker arms. I was under the assumption that you needed atleast the about threads that would equal the diameter of the locking nuts head? I will have to get a picture of what I have.

 

That doesn't sound right at all, never sen that happen with those heads... are you using a roller cam? what length push rods?

 

Roller cam and 7.300 pushrods

 

ok well I have 6085 heads and the engine builder told me he had to use stock lenght rods and not the .100 longer.. mind you I'm using edelbrock 3702 cam(non roller)

 

The pushrods are the correct length, we used an adjustable checker...
At the current moment we are going to put hardened steel washers under the studs to get it running and tuned a little until we can determine which route to go.
