Piston Question

They as in edelbrock. And running their 7177 cam. Your right 1008 gaskets. If this single piston don't work, then I will have the shop bore it out to .060 over and buy a hole set. Would love to get more torque. My plans are driving and weekend drag. Also stomping some punks on the street. One other thing if I go with these 285ncp would I be able to run a small shot of NOS. Or will they grenade.
