360hp guesses
The only things that got changed were, two of the springs tested a little low, so they got shimmed up, and the valve seals didn’t fit well on the guides at all, so they got replaced.
Seats were pretty wide, but runout was good...... guide clearance was on the looser end of the range(about .0020-.0025).
Flow: 4.0” bore, 28” pressure:
Lift—— I/E
.300—177/134
.400—221/153
.500—240/164
To put the flow in perspective....... bowl ported J head with 2.02 valve that made 90hp more than this motor did(also a pump gas 360).
Lift—— I/E
.300—183/131
.400—221/151
.500—223/158
