camshaft failure

[Too Many Projects]

There are solid roller conversions that will minimize the risk of failure and still have the "sound" that the tappets make. Find, or have made, a grind that is very similar to original and use that instead. Is anyone going to know if it's an original style tappet or roller lifter making the ticking noise?

My other 69’ Corvette 427/435 has a roller installed by the PO. But he had to put these wonky valve cover spacers on that I really don’t want on my new build.
I just assumed that the rollers needed more vertical space but maybe they don’t? Perhaps it was just the brand or make of the rockers?

Probably has roller rockers too with the adjustment for clearance at the push rod. They are taller than original style rockers. The roller lifter conversion is all in the lifter valley and makes no difference under the valve cover. The strap is the only significant addition and it prevents the lifters from spinning.

The car does have roller rockers.
Good stuff, thank you

Tuna Joe the reason for valve cover spacer is the poly locks on top of the stud more than likely, I'm wondering if you use new studs and crimp nuts on a roller setup would be any issue? I see no reason why they would loosen up.

Standard nuts will not fit into a roller rocker.

correct but roller rockers aren't required. I'm thinking OE rockers so you can run stock covers
