71 340 head choice (budget)

Yeah,no kiddin. Use what you got. It's a great foundation. Can we get some specifics about the "KB pistons"?

X2 the KB 243 in my 340 stick proud above the deck, I used a set of x heads and a 703 cam and it is kinda mild, idles nice with good vacuum.
Most likely going to change the cam up to something larger this spring.
