You don’t need to goto wildcat for a slant head. You can get one local, they are still at the wrecking yards. I’m local if you want some help.

by the name of Wildcat that manufactured a head for the Rover V8 engines which vastly improved flow. Based in England I believe so they probably did not take notice of the out of production slants.
