Ignore the springs supplied with the heads unless you have the SPECS for them and then compare the specs to the specs the CAM MAKER calls for , if they work , great , if not buy the correct springs .



See if eddy's spring specs match what your cam wants. If not, replace them. Either ARP main bolts or studs would be a good idea. Many people have gotten by without them so it is your choice. Girdle is not necessary at this power level. Pistons are your choice, go with something with a 2.060 or greater compression height.
