The current engine is knocking. As far as the new engine, from reading it seems like I'll need the gasket set from GM part number 89017824. It comes up as Head Gasket kit, but I'm not exactly sure whats included. I've read the top swap thread and I think I'm also going to need 2 orings 24501563 and a supercharger gasket 24503911. I was planning on keeping the rockers bolted to my current heads and just replacing the head bolts with some felpro ones purchased locally along with coolant elbows and whatever other basic maintenance items I made need. It sounds like the rest of my GTP engine parts are going to be fine to bolt on, with some possible clearancing to the oil pan.

Any one know whats included in the 89017824 kit? Any other major things I'm over looking using the 06 block?
