k guys finally pinned my winter build for my duster, 416 bottom end voodoo hydral tappet, pump gas, air gap, 4 speed, ported j heads, now the question how much would it benifit me to go up to a 2.05 valve or should i stay with 2.02:D
What valve manufacturer are you using for the 2.02? I would go with Manley .100 long chevy 11/32 valves and keep the current valve size but have someone who know's how to port and do valve jobs on mopar heads do that work.
Those heads can support pretty decent power, but it's real easy to get too much money in them compared to some new heads.
So just be careful of that.
