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 :dunno:

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