If he checked the old cam with clay as he says, then this time with checking springs.... there you go.
.118 with clay
.064 + .030 = .094 with springs accounting for clay method.
Intake clearance is said to be .044”.
I doubt there is .030” deflection at the point where the clearance issue is.
At the very least, I would verify it with an indicator.
Measured lift at point where V/P clearance is closest with checking spring vs measured lift at that same point with full spring pressure.
However much less lift is observed with the big springs(at that point), add that you the .044” clearance figure.
At 10* ATDC the tappet lift should be close to .200”. With a 1.65 rocker that’s .330” lift. Take out the .020 lash....... .310 at the valve.
A PAC 1243 is 550lb/in...... .550 x .310 = 170.5 + 240 on the seat is 410lbs at that point.
Does that equate to .030 deflection at that point with Dave’s parts? Only one way to know for sure.
And...... you’d need the correct “real” pushrods(not a checking pushrod) to get an accurate deflection measurement.
When I tested some 1.6HS rockers, the deflection was only .018” at full lift with 700lbs open force.
