I think you rely far too much on WD40; which is a crap product for every purpose except removing water (from distributor caps, etc.)

"WD40" also has "specialist products" which are reasonable lubes, penetrants, solvents and such, but they're only labeled "WD40" as a brand-name, they're not the original water-displacing formula.

You made me double check because I know I followed the ARP guide for my bolts for the newer Edelbrock heads. It definitely specified the ARP lube under the head, under the washer and on the threads. Then 100 ft pounds in three stages.

WD might not be the best product for valve seal install but done carefully with the plastic applicator on the stem would it really be expected to rip the seals?
