Plan on doing some circuit racing whilst still keeping it streetable.
I don't want to open the combustion chamber up any more due to the loss in compression. With a 351 calculated compression will be 10.5 : 1. If I go the 393C route with dished pistons it will drop to 10 : 1.
The heads flowed better with the inlet manifold than with the bellmouthed plasticine on the bare heads.
I'm trying to keep a lid on engine costs so that money can be allocated to the things that will make the car fast being: wheels, rspec tyres, rollcage, seat, harness etc.
