What would you want to see if I do a new engine build write up?

Depends on the end goal and desired RPM range I think. Middle of last year I did one for a Whaler, but decided to replace his peanut port heads with some closed chamber, small oval port heads that were cheaper than rebuilding his heads (they were in poor shape), and increased the compression of the 8-1 engine.

I have heard a few stories about guys making 600 horsepower with ported peanut port heads, but it's not that easy to port iron heads when so many inexpensive aluminum heads are available now. Not only that, dynos vary, so I am skeptical about how much power they actually are making, particularly in light of some of the 600 hp pump gas NA engines I have built.

I am currently ordering parts for either a 454 or 427 cubic inch mild engine for a 1959 Biesmeyer, that obviously won't require too much power for the owner to be happy, maybe a good project for a set of the peanut heads I have sitting around taking up space?
My target is 550 ft/lbs of torque and I'm hoping to avoid aluminum heads if I do end up ditching the current ones. My research says it's pretty doable without breaking my wallet I hope. We will see I guess . . .
