Hello I have a 1970 440 short block and would like to finish putting it together but I have a few ? about what heads to put on this engine. Pistons or L2355 I think six pack pistons .060 and a MP 590 cam. Also I have a max wedge intake do I buy the Indy EZ-1 Max Wedge heads and put the max wedge intake or sell the max wedge intake and buy a set of Edelbrock Victor and a Victor intake???I,am going to put this engine in my 1973 Pro Street Duster. Also was going to put a set of the 1968-69 big block A body manifolds on the car not headers. How much HP would I lose with these stock exhaust manifolds with 3" exhaust? Thanks
