Flat tappets push the cam towards the rear of the engine.
No need for a cam button.

|johnsongrass1||Fla tappets will center the cam. No need for a button. You might verify the cam gear has bearing behind it. I don't knw if those blocks have the thrust face machined in or not.|

Maybe the cover is designed that it doesn't need the button. The stock engines didn't use a button.

Getting ready to put the 70 LT-1 engine back in the '62 Corvette. I bought a cloyes true roller set and a Jeg's Alum timing cover. There seems to be a fit problem using a cam buttom (.640 length). My question is, the cam is the stock 70 LT-1 mechanical cam and lifters. Do I really need the cam button? If so, can I shave a little off the back to gain enough clearance to make it fit? how much clearance should it have.
