Project Junky Junk (or J^2, as Ross calls it), the gift that keeps on giving....
Had a few extra minutes today, so I went ahead and pulled the intake and heads off, just to see what everything looked like. Used my Craftsman 18V 1/2" impact and zipped everything off. We had used lithium grease on the intake gaskets so the intake would come off easy, so it literally took me 30 seconds to get it off.
The heads came off easily without much fuss. Had some copper shim gaskets underneath. Brought one piston to TDC and it was exactly .050" down.
Some good news:
1. Both heads ARE C6AE's. The sludge on one side made it look like a C8AE to me a few weeks ago. One head is for sure an R head. Not sure about the other yet.
2. A rough measurement of the cylinders reveal a 3.995" bore (with ridge) and absolutely no crosshatch.....LOL
Time for a rebuild.
I think I'm gonna just use the C6 heads. I was looking around for some small chamber heads, but I already have these and I'm sure they will clean up well. Looking around my shop, I found a set of 7mm bronze valve guides and some 7mm 2.100" titanium intake valves. Seems like a good start.
