Some decisions I've made:
I want a smooth ride around town and want to be able to run the cheap gas (87 octane).
Regarding the Aussie head, I'm going to take it to a mahcine shop, have it cleaned and inspected. I'm going to keep it stock and not port/polished. I am going to have the port diverted installed for the exhaust. Need to get one (need to find this part). If valve job is needed, I'll have it done and only add hardened seats if there has been deterioration and they are needed. I'll have it milled to ensure it is flat and can mate up to the engine block.
Regarding cam, I think I'm going to go with the 260. Very mild. I want a smooth ride.
Exhaust - headers definitely. I plan on using a two into one muffler with dual outlets.
Decisions left to make:
Carb is still undecided. The intake I have is also made for the head. It is set up for a 2bbl. I am contemplating a 4bbl as I expect I would get better gas mileage around town when only on the 2bbls, but would have the benefit of the full 4bbls when I need it.
Short block - haven't decided yet if I am going to have mine rebuilt or just do an engine exchange with Five Star. Either way, I'll need to supply the cam.
I suspect I'll wind up with a compression ratio around 9:1.
I plan to keep the stock rear end.
Thanks so far for the input. I've found this site very helpful, along with input from Mike at Classic Inlines.
Another step completed. I've decided to stick with the C4 tranny and not think about the AOD upgrade at this time. That will be a project for the future.
I've searched this forum and, from what I can tell, more people say the gain isn't worth the pain of a port divider. I don't want to spend the money on a "maybe" improvement. I'll skip it for now.
Really leaning towards a 2bbl. I figure, try the 2bbl. If not good enough, buy the adapter and try someone else's (it would have to be a good friend

) 4bbl and see if I like it. If so, buy my own 4bbl.
