Cam help....

My engine is apart for a power upgrade and I'm looking for a second opinion on cam specs. The engine was originally an HTM 850sc and for some reason it had a solid roller .I had the Edelbrock Victor #7760 heads ported by West Coast Cylinder Heads and now have 2.350 and 1.88 valves,the IE ratio is about 85%, the runners are now 410cc and they are in the 430 cfm range at .88 the intake manifold is a Hogan sheetmetal blower manifold with intercooler off a Sterling motor, its got a Blower Shop 14-71 and the carbs are Bigs 1240cfm Dominators and I switched to a dry exhaust. I want to run pump gas, 6300-6500 rpm max. It is in an HTM with a 1.36 drive ratio. Is there an off the shelf cam that would work well or if I need a custom cam what duration, lift and LSA should I be looking for? Thanks,-Jason

Sorry, the head flow was at .800 lift and its a 9.8 deck 565
