Squirt hole or no squirt hole?

Squirt holes are part of chrysler engineering advantage over other big three! My dad being a mechanic in the 60's @ a chrysler dealer, in 16 years never saw any cam related issues. When he left to open his own shop he worked on all brands and ford and chevy were the one's with cam failures. 454's and many ford straight 6 were the popular cam destroyers!
