I'm interested in a pair of ball-milled aluminum valve covers that have NO rail/oil drippers. Will I encounter any lubrication problems to the valvetrain because of this? Any and all comments will be greatly appreciated.

If the valve train supplies enough oil there should be no problem. Stock valve covers don't have these.

I guessing your other car is a Hyundai? Tiburon?
My folks are on their second Hyundai. Remarkable little cars. Very dependable. Their first was a very fun to drive Excell, and now they have a new very comfortable Sonata. Very will equipped car. I like it. Beats the heck out of my daily driver Celebrity or the wife's Caravan. Okay it's not a Vette, but what else even comes close?

Thanks for your prompt reply, Ken. I was under the impression that 82s came with the drippers. I haven't yanked mine off yet. As to wherher I own a Hyundai: no. Tiburon is Spanish for "shark". You know, as in C3s. The waters off Miami are full of the dangerous real ones and the streets are crawling with the fast plastic ones. It's all good...
