heads for 340

thanks for the insight and sugg. I dropped off a couple pairs of heads to the machine shop last week to have them checked and see just what they would need. After some looking i did find a set of 2.02/1.6 valves with retainers and keepers i forgot that i had, so that would be a little money saved. I hear ya on the new vs old cost, I have thought about aftermarket and have not ruled that option out, guess I'll wait and see just how much I would have to put into the old heads and decide from there. Unfortunatly, I am on a budget, so I'll probably have to go whichever way is less expensive, unless like you guys say its going to be within a couple hundred of new.
73swinger, I would be possibly interested in those j heads if you did want to sell them.
