I just tore a Target Crapper out of my 81 Truck, and was wondering what to use on my rebuild.

I have a 350 4 bolt at the machine shop which is a standard bore and crank. The machinest says every thing is good, no lip and crank is fine a hone and polish are all that is needed.

I have two sets of heads and do not know which ones to use. I would like to have a 350 Horsepower 350 when it is all said and done.

My confusion kicks in with the heads. One set is the 993 (big chamber heads) the others are casting #14102193. Both are 194/150. I am clueless on what compression pistons to use, cam etc.

I have not purchased any parts, would like to run on pump gas and take a 1000 mile trip if needed.

Many thanks to all that respond!
