There you go! Solid Flat Tappet and Head work is the ticket. Most guys run out of $$ doing the bottom end and cheap out on the Heads just to get it going sooner.
If you can swing a good set of heads it would be your ticket to power. These seem to make some good power. Nothing fancy but it gets it done on Pump Fuel. Pay no attention to the water pump not hooked up! Lol
