Instructions for cam removal include -
Remove accessories,
remove front cover

rotate camshaft twice and the lifters will be "retained" in their bores.
remove camshaft
Questions:
1 - Interested in exactly how the roller lifters are "captured" when the cam is rotated prior to removal.
2 - Also, after install.....what actually happens to release them back onto the lobes?
Are they pushed back down out of the bores by the pushrods or?
3 - Lastly - do I need to "degree" the replacement cam from the Aftermarket?...............or is the grind quality good enough not to worry about it?
