heads for 340

If you have to build any of the heads you have, you may as well get new heads. The RHS heads are very nice. What power lever are you looking for and what is your budget?

There is a wisdom to these words. :D
RHS is the screaming deal for iron heads these days......Brian at IMM has done some good things with them from everything I hear , so I would talk to him probably.
For Aluminum , Eddies are O.K. for the money.
They still might want some money thrown at them depending on what you want to do with the motor , but are a decent part at a decent price.
After you re-do a set you have laying around , it can get into some real dollars to do it right.
Guides , seats on the exhaust if they don't have hardened seats , quality valve job and minimal porting , springs , keepers and locks , surfacing , magnafluxing.......we're knocking on a grand easy now.
Probably a little more.
The aftermarket is catching up to small block MoPars and it kind of runs parallel to the " should I recondition stock rods " debate.
There are a couple good options out there now.
