Hey fellas, I am building a 318. Using, KB's167 pistons, Federal Mogul Moly rings, Scat I-beam Rods. Machine shop balanced the rods and pistons and the Crank, the block was bored and hone .030 over at zero deck. Now for the heads. I will like to be in the neighborhood of 9.5 to .10 compression. I have been looking for the ####302 casting heads because they are the close chamber type but I can't seem to find them. I found 1964 commando heads from a 273, the guy said that they are close chamber and they will work as well as the 302 casting. Can you guys tell me if these heads will work as well as the 302 castings? Thanks in advanced
