I'm not sure of the exact specs, but you can see it had some upgraded parts. It has heavy duty pushrods, bigger rockers, studs, guide plates (regular short v/c's wouldn't fit). The intake valley had been coated too. (that has to add 10hp, easy ) It runs real good, has nice pick up, but it sat for a long time and it smokes a bit. I'm sure its the valve seals. All that's coming out for a TBI set up. I'm curious to see what else is in there when we pull the heads off.
