A pox on both their houses but not much choice
no quench with either
so 9:1 with that 262 lunati voodoo should get the intake down to .006 around 57 ABDC and stock gears and converter
the 10:1 should have a bigger cam and a hp converter (and gears)
do the heads like have been said seat and 60 degree about the same width 72 and a little 80 then blend and a top cut
me I'd run cut down 2.02 valves with a 30 degree seat where the existing top cut is now with that cam flame retardant on
carb? can you return it would be ok with 10:1 and much bigger cam and low gears but overkill going to take some tuning
simple AVS would be plenty
