good points 66
most likely could just need a hone but do not bore any more than necessary
want more cu in stroke it
915 heads I have several sets but you are in florida
915 by itself will not give you any quench
guides, seats, valves vs new heads
I D Dished the 6 pack pistons to get the CR I wanted with the closed chamber heads
check right now to see if you have weight on the dampner- if you do you have the heavy 6 pack rods
do not use them use LY rods with Mopar Perf SPS rod bolts and LIGHT pistons- makes a big difference
1.81 valves with hrd ex seat BVVC
or use those heads which have induction hardened seats , keep the stock 1.74 ex and the KB quench dome pistons
see if stock timing chain- see the nylon in the pan
measure compression height at all four corners B 4 Pulling pistons
you have the best carb for the street but you can go lighter on the manifold

for a street car check the torque difference with the cam change at 2500 and 3000 vs the big gain at higher rpms
as IQ says a dual plane would make a big difference
be real sure that you get what you want for your build
