Rocker to retainer clearance is good on close & open.

Guess it comes down to the chances we take and how much we want to spend to minimize the risk.

Yes and remember the age of block and heads which is likely 1966 or 68 production

Seems like hemisphere aren’t made for long life(like big block Chevy )
Puts a lot wear on your guides & stem’s when you aren’t true
I choose to run the least spring pressure while many run a ridiculous springs even on the street
The racers love talked to have ran stock rockers
Unless you spend $$$ you’ll be wasting your time for 7000 or less

When you take your time and do it right there is longivity. Whenever I adjust the valves {solid roller}they just stay the same with no adjustment needed.
Street driven and once is a blue moon I'll get to the track.
