get the book on the car that should tell you

Not neccassrily in this case being a modeified engine, book is based on stock specs.

There is one person here I think maybe can answer that question, otherwise I would consult a machine/speed shop or maybe the tech counter at Jeg's or Summit

One thing tho, you bought the car this way right? If so, check the gap off of one of the old plugs
