Take the heads to billy Tim. Ask him to have his dad take them to be flowed.
If it was my stuff, I'd have billy set up the valve springs and check everything out.

Are those heads "as cast"?

the heads as far as ports are, the rest was done last summer to make them right, they had many issues.... all new valves, grinds, springs were ok, retainers, keepers and guides all new....

Is that a bazooka bass tube mounted to the front of the starboard engine? Or a rocket launcher?

My 509 dynod at 684hp at 6200...it did have very good heads though. I think he could make 700 at 6000 but I do not see a problem spinning it higher.

Well, you need to determine what average piston velocity you're willing to live with and build to that standard. Nascar and F1 engines, IIRC, both have similar piston speeds but note the RPM difference.
