Oil restrictors in a SBC, help

[Richard Kensicki <richk@spartajunction.com>]

Anyone have an opinion on using oil restrictors for flow reduction? I've 
pulled the motor out of the Vette I bought to get to the rear of the 
block just to check this.

The engine is a  race motor and ground down the the first 2 lobes on the 
cam in a short period of time. This original cam was a solid lifter cam. 
The second owner found the cam problem and replaced the cam with milder 
hydraulic cams; twice; and suffered the same problem along with severely 
worn lifters. He never checked for oil restrictors.

I know the theory of what the restrictors accomplish but does a stock 
SBC have any type of restrictor plug? I'm replacing the cam with a solid 
lifter cam with the original lift/duration. Should I keep the 
restrictors I have? In the Stef's Fabrication catalog their restrictors 
use an .060 hole to reduce flow by 70%. The ones I have have an .093 
hole. Will this be OK?

Have more questions but will hold off until tomorrow.
