Shake, rattle, and roll!

Welp. I can't find my old thread ;) so i'll start here :D

I was posting about the rattle noise I was having, well. with the ticks and rattles I figured I would let the old gas burn, and fill up with some new gas.

I went with a full tank of 93, and a gallon of 103 ;) it still has that damn rattle....

good news is that tick I thought was my exsaust... ummm, wasn't. I pulled the valve covers the other night. I had 2 lifters on wrong :doh:

but now I'm still worryed about that damn rattle. Timeing is dead on, well, as dead on as I can get it. air / fuel good, vacuum is at 15 <probubly be able to do beter>

I think maybe i'm one tooth off on the timeing chain????????

maybe????? any Idea's guys? this is driving me nuts.
