406 with a177

I have a a melling high volume biilet gear oil pump 3/4 inlet 7 quart moroso pan baffled and windage tray, high flow water pump from flowcooler 3 core rad with steel fan and a corvette clutch fan ,3/4 hub vs 5/8,180 thermostat,during the hottest of summer it reached 190 in traffic,other than that it stays between175-183 constant,cam change and and a dished piston forged,I have RHS aluminum 72cc heads motor is afull hydraulic roller already.
The 177 though does not have teflon coated rotors where as the 144 does ,does that mean it will not seal as efficiently as the smaller one given any one rpm setting,I realize for every rpm it will draw more air than the 144,jetting wise and power valve any recommendations,it's a got a M-21,3:42 rear gear,weight is 4000lb'scam will be 233/241@50 ,530 int/545ex 114 lsa,110 ,lca ,I now have a holley ultra hp 750 cfm with electric choke but I wiil need to change the power valve to a boost referenced one as well as the accelerator pumps to 50cc from 30cc which it has now as well as the jets i'm running 68 primary and 74 secodary the car runs great and the A/f ratio is 13.5-13.9 at cruise and 12.1 under load full throttle accordiding to the dynojet when I had it dynoed in may,
Again if any one can steer me in the right direction with the 177 weiand as to P/V and jetting that would be greatly appreciated.Thank you everyone.
