There's a GM cutaway picture in this forum, about a year back, which shows the newer roller cam follower. Not sure what the thread name is.

The hydraulic lash adjuster is on the left, surrounded by a cutaway oil passage, the follower with roller has 1 leg on the adjuster and 1 leg on the valve tip, while the cam lobe rides on the roller. Elegantly simple.

BINGO......a-searchin' e will go, a-searchin' we will go, high ho the Derry o' , a-searchin' we willgo....!

Click on the pic and scoll in.
