Just wanted to say that this is my first post on here and i hope to get some answers.
Yesterday i swapped out my cracked and old small log head on my 1968 200 for a large log 1969 250 head. I am aware that this head is not the best swap but it is the only one i could find. I had it checked for cracks, I ported it, had it decked 0.060 to get the chambers down to 48cc and had the valves resurfaced. I felt confident doing this as it came directly from an engine that had never been apart (Original ford steel gasket) and my 200 that is in the car had previously been rebuilt and likely had the block decked.
Now to the issue. Ever since i bolted it into the car it has no power. It revs much faster, louder and quicker yet i feel like something isn't right. The carb is a weber 32/36, It has HEI ignition advanced to 14* (Yes i checked TDC when the head was off, the balancer hasn't slipped)
Adding to this is that whenever i take the PCV out of the valve cover and block it with my finger the engine always nearly dies.
Help me out please.
