... well, just thought that I would call Helen to tell her that Andy said hallo

.I actually don't think the flow numbers for the RHS 215 heads are too bad - I've read posts on forums where they support 650+ HP.
The dual plane air gap manifold has tiny, tiny ports compared to the ports in my heads. No port work was done by the enginebuilder and it still came out with 525 HP which I think is not too bad.
I'm not going to make big changes to the motor this winter, so my plan is to start out with the dual plane, to which I now have done some quite extensive port-matching. I'm quite curious how porting, and solving the problem with the intake gaskets that was badly mismatched, will affect engine power and general behaviour.
Then I'll try out the victor jr or the equivalent ford motorsport V351 possibly with a doublepumper to feel the effect.
Regarding all the other suggestions - they will be considered for my next engine build - probably a Dart aluminum block based 438 clevor.
