88transam

Hello! I have a 350 block that I am building I only have a crank rods and of course the block well it’s a 3970010 block from a 78 one ton dually and I was wondering what is a good head that I can get for cheaper I am on a budget I am also looking for around 500hp from the crank and I I would like to get a 64cc with 202 160 valves if anyone knows of a cheaper head that still performs good just not for almost 2 grand like some dart heads
