Howards mech roller w Comp Rollers

jCan I run a Howards mechanical Roller with your Mech Roller lifters?
I like Howards because A). they will custom Grind a cam for me at a reasonable fee plus they have one pretty close to what im looking for already. Heard good things about them
B). They are helpfull and knowledgable at the shows, phone. much more than my Comp Cam experience so they got my vote!
