I see a lot of opinions. That's great and all but how many of these opinions are coming from guys who have built engines, ported heads, and have ran their combos on a Dyno after doing their own work. I'm sure it's a small percentage. Unfortunately when building an engine there can be a bit of trial and error. No one has a crystal ball. I've seen heads that looked great on a flow bench not work all that well on an engine. I've also seen combos that look like garbage on paper make great power. When we did engine masters we would order several cams from different manufactures. Multiples from some. You have an idea what will work, but sometimes reality is a different story. You have chosen an expensive route to chase dyno horsepower (cylinder heads) Unfortunately it didn't work out yet. That's part if the deal. You're in it now. At some point though if you need the number, sometimes the answer is in the simpler stuff (if the heads are decent). Camshaft, camshaft timing, intakes, intake/plenum work, carburation, spacers, etc. those may yield the results your looking for, it's just time and money unless you're coping an existing proven combo. I'm confident you will get there and I wish you luck.
