440 heads whats better??

i like where your going with this nitrous idea.. but id probably end up blowing up my engine with that one and be back to square one. But who knows, maybe one day!!!

what about an average cost for mechining my 906 heads? Could i fot that in the budget?.. not a lot of experiance with these things.

Nitrous ( 125-150 shot), is cheap,easy,& addictive. I would pay attention to fuel line size (1/2"- AN -8 size), fuel pump quality ( a high quality Edelbrock/ Carter mechanical pump, a GOOD electric pump, Holley blue/Carter HP 4601 electric...), and at least a good stock electronic ignition . MSD/Holley digital box,even better. Every fifty ponies of spray, minimum 2 degrees retard total timing,@2500-3000. As for budget heads, check out Edelbrocks EZ heads line,& 440 Source's Stealth heads.
