running a NX 150 hp nitrous system on a stock bottom with 80,000k on it, i just bought a set of heads edelbrock performer rpm's. my question is whats the likely hood of blowin this motor up and wreckin my new heads, witch are to nice to see get smacked by a piston. should i worry ? or bolt them on now, they are originally goin on my 347 stroker im building at the moment but these heads will breath nicely on the 302 in her now. is it worth it or wait for the motor without the juice? thanks for any suggestions keith
