Had my X heads ported - results

I would like to know what the acid porting did! Always been curious about that process. Did the ports look a certain way? What was the valve job like?

A S/E valve job has a LOT of science and skill behind it so these castings must have made the cut. If someone went to the trouble of acid porting those particular castings they must have showed better potential than the other 900 sets that were gone though before those were chosen.

Exactly Correct!!

I have 200 sets of the part # Heads we have use our various Stock/SS cars and have disposed of at least another 100+ Sets.

You would be surprise how much the same # heads vary on a flow bench = Also true on the intake manifolds!!

Often there are as many a 10 cars in each of our classes - all within a .1 of a second.
In Denver @ Nationals some year back - I won a class race against a 340 Cuda
heads up by .0001 of a second true margin of victory. You could not see who won
with a naked eye! For every second we are on the Track = Ther is a Week's work in the shop!!
