Spark Plugs

This is my setup right know.
Fresh stock bottom end rebuild
Steeda 19 cam
Gt40 intake
This is a link to the Heads that i have in the car

Can you please tell me what plug you think would be best for this combo.
I am having a hard time find a long shank plug that would be good for it with these heads.

You will have to experiment with heat ranges to get the exact combo. There is no one plug thats a "One size fits all" It has a gasket seat and .750 reach and is where I would start. On heads like that it's always my starting point and sometimes the final point.
