Corey, if you intend to beat on the engine much down the road, keep in mind 
that the famous 'core-shift' that 351-C blocks are infamous for, also 
affects the cylinder heads and it's much harder to determine. So cutting pockets 
for different valve springs, surfacing or porting all can have unintended 
consequenses in some castings. 
Plus as we get older, handling a 22-lb head at full arm-stretch in a 
Pantera engine bay is much simpler than dealing with a 62-lb iron casting.... Good 
luck either way- J Deryke
