Hi Woody,

You have center-bolt valve covers......which means you'd need to cut around the holes in order to access the rocker nuts yet still have enough meat to bolt down the covers?

I've never heard of this being done, and I suspect it won't actually work because the metal would not sustain enough hold-down pressure to seal the gasket.

What I do is warm up the motor, take one cover off, adjust, then replace cover. Repeat on other side. Then I let cool down and simple green and hose down each side.
