Well I picked up my bike yesterday and it's a huge improvement from the original state. Pretty much the neck snapper I was looking for. I'll post the changes that took place but I need to get 500 miles on it to really let it rip and give you a seat of the pants report. The ignition, pipes, and carb were previously done so I'll just give you the basic motor work.
Cylinders were shortened by .045 (which means -.045 from where they were so actual finish length may differ)
Positive deck by .010 (piston above cylinder)
.010 base gaskets and .030 head gaskets.
Woods 9F cam installed with new bearing (.650 lift .256 duration)
Travel limiters installed due to fast ramp of cam
Tappet blocks clearanced as well.
Cylinders re honed with new rings
Manley .650 high lift springs with custom lower spring collars.
spring seats machined/complete valve job
heads cc'd (90.8)
some combustion chamber modifications/other headwork
intake manifold machined .035 off per side due to cylinder length reduction
static compression set at 10.8:1
aggressive timing curve set with crane HI-4 28 deg. BTDC and rear cyl. @0
rejetted carb (set a little fat for break in) 82 main 33 int.
