think about it for a moment... this is a insignificant amount of money to not only verify the manufacturing specifications of the components but also avoid damage of costly engine parts.

i'd much rather spend that dough and time to degree than the whole nonsense of bending a valve-- so now you're gonna need a valve, pushrod, head gasket and to take the whole front of the motor apart again.

people always seem to have time to do it twice, never time to do it nice.
