A mild cam in the 218/224 range or even smaller.
I know you are set on that motor but IMHO a later year 1 piece RMS full hydraulic roller cam with vortech heads would, be what I would have done
IMHO even with a cam, that motor will be in the 275ish HP range unless you get a more modern head. Heads and cam should be a compatible package. One without the other really leaves a lot of HP on the table

Any chance the heads would do ok with a bit smaller valves than the 2.02/160 you recommend or is that the only bigger step up. I'll have to call summit to see what they'd recommend for an aluminum head and cam I guess. I've heard they are good to chat with?
