Me and Moper both have said the same thing on the push rod length. Yes you will need custom/shorter pushrods. And when you take that much off the heads I would think you would plan on Roller rockers also.
I always read this about the custom pushrods(why???) when you mill heads say .100
I bought a set of 440Source heads and milled them .100 to reduce the CC volume to increase my compression.(had dif opinions on wether this was a good idea-the end result was i picked up 33hp w a larger cam)
I used the old mech pushrods and adjusted the lash with my adjustable valve gear. no big deal*Crane Roller rockers
