What do you guys recommend for a plug on a 305 mildly built?
416 heads with larger intake valves
Performer intake and 600cfm carb
Sanderson headers
Performer cam
MSD distrib and coil
Accel wires
Zero decked block with Speed Pro flat top pistons
I am looking at accel short plugs but I'm not sure what heat rating I should be looking at. Any ideas?
