Work has had me busy last few days, but did some work on 962 tonight.

Port durrations stock
E 156.8
T 113.8
I 148.6

I don't thing I want to make any big changes on durrations maybe a few degrees more on transfers, a couple on the exhaust and widening out the exhaust should give enough blowdown area. Intake I think just widening and durration increased what ever lowering the jug 0.025 will add.
