Lots of compression, water injection, polished chambers.

Forged pistons Dave? Why? Heavy IMO.

Tri-Y headers or magnum manifolds.

Gasket matched intake ports on the head side only. If using iron maifolds on exhaust side? Gasket matche the manifold only. What you are attempting to do is cuase an anti-reversion effect. I did that on a slant for a friends 833OD '81 B100 van that is a work truck. Lots of torque!

Mild porting. Excellent bowl work.

I'd be leary of running an RPM intake in Virginia in the winter time with a carb. I have ran my van with a Offy Dual Port with the heat riser block off in TN. It warms up really quick. It isn't an airgap.
