Solid rollers with off set push rod hole issue.

Assuming valve springs are set up the same, spalling on the intake only suggests it's an issue of the larger forces involved due to the heavier intake valve. I doubt the heat treat or core is any different intake vs exhaust so we're back to an insufficient heat treat or material for the stresses involved.

Spring pressure are both the same on intake and exhaust. Not sure if I should have little more on intake as it is boosted. Valves are 2.05" in & 1.65" exh , 11/32 stem with tool steel retainers and AFR/PAC springs. Waiting to see what cam company has to say.
