MSD ready to run, with rpm heads?

Is anyone running a MSD ready to run distributor, on an RB with edelbrock rpm heads?
Any clearance issues? Thanks!

Anyone?

I have Edelbrock RPM Performer heads on a RB. I had to clearance the head a little with a grinder to get a Holley HyperSpark distributor to fit. I have not had any ill effects from the clearancing. I just took a little at a time until it fit and would rotate. The Hyperspark doesn't have a vacuum advance canister.
I seem to remember an adaptor available in the 70's to raise the distributor above the head, but that was a long time ago and CRS.

I'm running a MSD 8546 with Eddy heads with no clearance issues.

wasn't that adapter used on B blocks to use the RB distributor ?
i remember seeing a blueprint of that adapter somewhere, so that it could be fabbed up by a person out of aluminum bar stock.

No such thing as MSD ready to run distributor for a big block. Wouldn't fit which is why they don't make them. SB only.

This is what I have now, but I’m looking to go to vacuum advance.
