Jerry's style of (small block v-8) valve cover "spreader bars" - washersFor 1954 and later 235 and all 261 Stove Bolts
Luckily, my four-stove-bolt valve covers do not leak.
But, I would use those, if I had warpage leaks.
My original-style 4-screw 235/261 valves cover washers look like the ones in the attachments below (available on-line), but, my "oblong with-points" washers are more symmetrical.
