The horse is dead

It is great to be confident but it is also great to be confident and correct.
It is arrogant to take the attitude that says if you're not willing or able to modify parts to fit, you shouldn't be working on cars.
The OP states that he is willing to but wasn't given the option.
Apparently I'm qualified to build a 360 with a 6-71 blower, build Shovelhead and Panhead strokers (you wanna talk about modifying parts to fit) and a whole pile of V8s from different manufacturers, but I'm not qualified to install 1.6 rocker arms! Hahaha what a fruit cake.
