Thanks for the advice & offer to help!! Looks like I'm replacing exhaust valves & heading to my machinist.

I have a "little" problem. Engine's out of the car...due to an ahem, "miscalculation" on my part, actually make that major brain fart, I over-adjusted the cam timing on my motor & caused piston crown/valve contact on start-up. I put a substitute L28 in my motor's place in meantime, but now I'm faced with varying possibilities on how to go about fixing my cylinder head. It's an E-31 head, a good one, so I don't want to toss it. Only the exhaust valves were contacted. The bottom end looks fine...pistons aren't damaged, just slightly nicked/scuffed where the valve edges hit. Everything I know tells me to replace all the exhaust valves (I do have a spare set of valves). I'm assuming even the slightest contact will ruin the valves. Anyone ever have an experince like this? It's not a catastrophic failure, just a hiccup. But I wanted to pose this to the forum to get some advice so I can cover all my bases...Thanks for any & all help. TG

Somebody more knowledgeable about these things should check this out. The seller's user ID is "forjunny" and it looks like this part may be a scam. It's auction description has all the hallmarks of one: too much elaboration, too much hype, not enough technical explication. Let's slam dunk this asshole if he thinks he can convince us that this is an "easy" LSD conversion. I personally would want to find out that this item is not all it's hyped to be after removing, disassembling and re-installing a rear end (not fun). This part looks to good to be true. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33731&item=7907869468&rd=1

Here's a link to the eBay aurction for this item. It's previously used, pre-programmed for a 3.2 litre L28 conversion. Check it out! http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=1875365354
