[Fot] head selection.

FOT
I am preparing to build a high performance engine for use in my 56 TR3. Not a
fully tweaked one, but one that I can take to drivers school in the spring and
begin to campaign in vintage events. (Plans include updating to modified TR4
front suspension and TR6 brakes as well.)
I have purchased a bare block and crank sourced from a TR4A to serve as the
basis for the engine build. Question is, what is the preferred head for my
application? I plan to do some mild porting and use the larger than stock
valves. I have a set of the short-throated HS6s and a 4A intake manifold I'm
hoping to use. Does anyone know if this will result in a hood clearance issue?
I would like to make an intake plenum with ducted remote filter, though I
suspect this would not be allowed by most vintage racing sanctioning bodies.
Additional comments or suggestions would be appreciated.
Thanks!
