Asking Bob Allen's adivce regarding an 'A' engine is akin to asking
a 'New Yorker' for directions ... all its gonna get ya is 'abuse' ... ;^)
IMHO, Steve Darby's Cross-Flow Heads are *excellent* ... a radical
increase in air flow and an increase in CR beyond that possible with
the stock cast iron head ... if ya have the disposable income, go for it.
OTOH, the porting mods outlined in Peter Burgess's book will net ya
a substantial increase in air flow ... stay away from the racing mods
and larger valves 'cause they will have an adverse effect on port
velocity.
