Holley Strip Dominator vs. Edelbrock Victor 340

Anyone have any Strip Dominator porting tips?

The spread bore opening makes me think it should be epoxied to a 4150 though I don't really want to get involved with that.

Perhaps a fancy spacer would be a something to try instead.
Mine came that way, if it wasn't on the mill, I could Mike stuff and take detailed pics.... I'm Sorry...
