most aftermarket cams will use a smaller base circle in order to get the most out of a grind....also your talking about removing 30-35 thousandths off the deck of the head and running a head gasket that is 20 thousandths thinner compressed than your stock gasket...you cant just assume what pushrod length will work...you need to check it...
what a lot of people are failing to realize, is that most heads/cam setups dont need anywhere near 300 CFM to make the power levels many desire...

well i have a bunch of pushrods here in various lengths, i just check how many turns past zero lash (piston @ TDC) until 22ftlbs of torque with .047" being about 1 turn. with stock,comp 850's,caddy lifters etc etc. i like to see.070-90" preload cold. with morel lifters and comp r's i like to see around .025-35" preload.
