Good Day I am opening my heads and was looking into the bigger valves,any advice on who or where to get some or what to stay away from. I need the 2.14s and the 1.81s. Thanks for any help. Dizzy:blob:
Don,t do it,use the stock size and have a real head man do the heads and they will perform better than going to big valves,unless you have a 500+ cube motor,Mrmopartech
They help on even a slightly warmer 440, but you need to open the bowls and open the pushrods pinch a little. Mancini or summit racing will probably get you what you need
