Adding up the lift of a COMP 260H cam (.440") only with the Magnum heads' 1.6 rocker ratio that .440 lift, becomes .467;
Does anyone here see where I would have issues at that level of valve lift with valvespring retainer bind? Would I need to shave the valve spring towers on the heads

also what are the springs that come with the "assembled" EQ 318-B heads? I got these right from EQ via atheir Ebay site, not from Hughes or a Cleawater Cylinder Head type place.



Retainer to guide clearance on the magnum heads is usually good to .520 lift.
