Valve covers

Mopar Big Block Talk

Are the Jensen valve covers small block “Square hole” Chevy covers or earlier “Staggered hole” Chevy covers?
I've got a Rover V8 in my Jensen-Healey and I found a company that does adapters but the choice is as above.
16 valves but 4 extra pistons.

you have Chevy 383 or 440 engines in Interceptors don’t you? The jensen valve covers were put on after the engines were delivered so they must have a Chevy bolt pattern. According to the adapter supplier there are two types staggered or square.

The 383 and 440 are Chrysler, not Chevrolet.
