That's why most guys don't go with the taller valve covers. If that's what you want, find a good machinist and design your own. I haven't seen anyone's fix for this as of yet. If you do design one please post your pictures and maybe make a deal with your machinist to produce them for the forum.

i know a bunch of people have these valve covers. i went with them cause i couldn't afford to buy new stock ones. i had a lifter fail a few yeras ago and sent a pushrod into it cracking it. i epoxied it but it leaks and looks like crap.

Josh,
I run the proforms above and had to grind the lower back side of the Alt. below the bearing to get adequate clearance on the 95 but it cleared fine. I did make a block to raise the alt. a little though due to the smaller ATI damper I run in order to keep the stock belt and allow easier removal of the valve cover without moving the Alt. I have a few general pics I can e-mail you showing the install but not much in way of the Alt. grinding done if you PM me your e-mail address.

I'm running the same ones. I simply marked the area of interference - a quarter size area - with a Magic marker. The removed the alternator, taped off all the openings and used my high-speed Makita to grind down the offending area.
It didn't take much grinding and only took a few minutes. Only downside is the alternator probably wouldn't be accepted as a core should it fail and I needed a replacement.
Sorry, no photos but it's a piece of cake to do.
