I think aftermarket has 1 part # kit for rear cover and crank seal and new housing now .

.i think the other biggest one would be a harmonic balancer puller they require kind of a strange 3 jaw puller type. you can make an installer out of the old boltAny other ls tools I'll need..?
I went super fancy on my last head install:The torque angle chit seems to be a bunch of crap to me. I see no real reason for it even after watching and reading the explanations. Doesn't make any sense.
Years apon years of stuff was built precisely and fine before that started.
I also can not see any way for an torque wrench to tell me rotation of the bolt.
The dial indicator deal you put under a ratchet yes. But a digital one I don't get.
Unless it has a 1mm precise gps built into the handle, how does it know how far the bolt has turned?
