Specifications:
I was wondering which type of spark plug should I use with these heads. My engine is a 360 stroked to 410 cubic inches cam 600/621 I have already changed the springs not sure which spark plug to run. any help would be great thanks
Do these heads use OEM rocker arm assembly? Will you need different length push rods? Will the springs handle a .564/.576 mechanical roller cam running a 6-71 supercharger?
