Do not make a bigger hole have it machined as an oval. Could do with a small round stone and dremel tool. Tape up inside cover to make clean up easier.

Well I tried one more set. I drilled out all four holes two drill bit sizes bigger than stock. Not only would they not fit on the set screws but I put factory valve covers on and they fit except for hitting the roller rockers. I am sucking it up and buying the Edelbrock. Donít even try the procomp or trans dapt brand they simply do not fit
