Wont crank with the plugs in.

With the plugs out it free- wheels easily. I dont know whats up, compreession SHOULD be 9.7:1. New starter and battery. I checked the lash twice. Ive been building engines for a few years, and my racing buddy has been building em for 20+. We are both stumped.

Trick flow 190 heads, with a trick flow cam. 1.5 RR
TRW flat tops Eagle rods.

It will crank till a cylinder comes up to compression stroke. EVen if i take em all out but one plug it will crank till THAT cylinder comes around to compression stroke. Im thinking its the jumper cables i have rigged up to the starter arnt provideing enough amperage. The engine is on a start up stand, with no tranny attached.
