440-3 motor motor home engine has heads with zero performance potential,

As cast?
What heads on top?
Define performance potential.

I’m thinking 452 heads. Known to be able to be ported to and slightly better than 300 cfm. @IQ52 can show you the way.

Well, you didn’t think a Chevy 454 head gasket was going to be used now did ya?
