if i run it just off the wastegate which is 9.8 psi it has yet to do it.i called edelbrock and told them what was going on and they said if i was spinning more RPM and more boost then yea maybe valve float but being im trying to pull 6200RPM and only 14psi he said hes almost 100% sure its not the valves.
one on the guys on here bullit proof had the ford racing svo heads or whatever they are called and hes has no issue with his so i dont see how the edelbrock would fail so now im lost i have no clue what else to try
