Why spend all that money on a stroker, then scimp and get subpar heads.
Either way, just like primetime5.0said, the Comp Cams ProMagnums are good and you will need tomeasurefor the correct pushrod length with an adjustable pushrod and solid lifter or hyd. lifter converted to solid.

RE: rocker arms???
if you run guide plates run a hardened push rods, and i recomend running guide plates if your running a higher lift cam because you will be running stiffer then stock springs, bent pushrods can be a disaster

Heres the thing....I ran a set of Comp Cams ProMagnums 1.6's and for the longest time I had this ticking/tapping sound all across the board....did a million different things to resolve issue...finally got so pissed pulled the motor out and its sitting on my garage floor....I spoke to a tech at Holly (heads Im running dont ask why) and they said some heads "prefer" to run a certain Rockers.....so if you buy Patriot heads ask them if they recommend a certain rocker...then buy that one....dont know what my issue was maybe retainer clearance issue or some crap? Or I just suck....LOL

I have used ProMagnums on several engines and different heads and have never had this problem.
