I just recently purchased my 235 from a guy who decided to go ahead and put a 350 v8 in his 54 truck. My 47 3/4 ton already has a 350 sitting in it, but it was put in very sloppy(by previous owner) and has never been finished. That is why I am considering this 235. I have a new old stock 1959 235 head that I was told made greater compression. Can it be placed on my 54 325 to increase hp? Will it interfere with valve/piston clearance?
