Built 6.0 N/A motor spark plug help Hey guys, my car has a 6.0, with texas speed prc heads, texas speed pistons, crank, and a bullet brand cam, long tube headers.
Right now I have NGK TR6 plugs in it, I have a slight miss at around 2-3K rpms.
I don't know that it is plug related, car runs great at WOT, the slight miss just happens at cruising speeds.
I believe the TR6 is one heat range colder than stock. I would like to try the delco iridiums, but I think they only come in the stock heat range. Should I try the NGK TR55 iridiums, or would they be too hot for my motor? I'm just wanting to go to an iridium plug that will last a while, and I'm just not sure what heat range is best for the car.
Thanks guys.

LQ9. I know the heads are PRC, seen the brand on them, but don't know the specs. Cam is a bullet custom grind, but not sure of the specs, very lopey idle. I'm not sure what intake is on it I'd like to know, car was built when I got it.

SPG and Coil Dwell Hi Dogz, I would like to know your Spark Plug Gap ?
The miss-fire could be related to ignition, what is your coil dwell ?
What coils have you fitted ?
What is the AFR when the miss occurs ?
What is the condition of your SPW ?
Your could use an ARF meter, an EGO read out.
