318 340

Nothing stock. By the time you get them rebuilt and cleaned up you couldve bought an aftermarket better flowing set. You can get a done set from Indy which will be the RHS heads (cast iron), however, if you go to summit racing you can get yourself a set of Edelbrock aluminum heads for cheaper (60779, which are closed chamber 63 cc heads, I have they on my 340). But you'll need to know which pistons you have i.e. are they flat top, dome, or dish, as well as if they pop out of the block.
