Could be that the fabbed valve covers/rocker covers are there because of clearance issues.
Do they have baffles inside ?
The critical measurement is most likely from gasket rail to baffle, not sure if that dimension is published on the MP covers.
I suppose you could double up some cork gaskets, but I've never cared for that.
I used to make the spacers, but was losing money on the project.
Medici Mfg makes them now; more expensive, but they're surviving. They're on Ebay as well as directly, IIRC.
Thank you. I'll have to keep that in mind and refer back to this post. I see that some of the Big Block ones have Baffles inside of them.
