The spring pockets in my AFR heads are cut for 1.530 O.D. springs. The beehive springs are 1.290 O.D. which allowed them to move all over the place in the pocket. I installed a set of locators which positively locate the valve spring and center them over the valve stem. Not sure if this was causing a problem or not but with .602 lift and spinning past 6500 rpm I'll take all of the valvetrain stability I can get! |
