Sealing up valve covers

Project 53 (My Avatar) 318 now has 27 K plus miles since total overhaul back in 2019. The oil leak problem has become so bad to the point that the starter got saturated and left me stranded a while back..... The oil leak was noticeable (with way too many
irons in the fire in my life) but has got to be a nuisance and now that life has slowed down for me I am now on a mission to see if I can stop it completely. As previously mentioned by Trail Beast the V.C. gasket sealing rails on Cast heads can be rough to even having high points in the casting from the factory. If I were honest with everyone I never even thought to look at these sealing surfaces when I was bolting on the heads...... but the more I look at it the weeping effect through the hold down bolts (combined with heat) just might be the culprit as all 4 corners on both valve covers are doing the same thing.... plus its worth noting that oil does collect in the corners of the valve covers. Through my 50 plus years of owning vehicles I don't care what brand was on the hood a mass majority of the older engines of the past leaked or wept oil somewhere. Thanks to a lot of special knowledge on this site and many great mechanical minds we will overcome. Texas Red
