I have a set of scorpion full roller rockers that will fit a 2.8/3.4. Normally these don't fit under the stock valve covers since they are so big but I had a valve cover spacer water jet to give a bit of extra clearance under the cover. I also have longer valve cover bolts that go with it. I ran these for about 5000 miles including a trip to the 30th anniversary in indy from detroit with no issues. I have my 3800 installed so just getting rid of the parts I do not need now. These are over $200 new and the spacer cost me about $100 but I will sell it all for $200

I'm guessing the spacers are made of aluminum?

Anyway, I'm very interested in this. PM sent.

I would like to be next in line.

Sold and shipped. Thanks for the interest

All the parts have arrived, and everything looks good. I'll have some feedback for ya shortly. Thanks!
