This is really nice to see real world. Don't take this wrong, please don't. What was the costs of this package to get 11.9@ a Buck16? Not including the body and chassis mods.
11.60? The heads were bought used and after milling and porting I had about $2500 total in them. Diamond pistons, Eagle SIR rods, balanced rotating assembly and good machine work. I'd guess 6k at the time, about 15 years ago.
The heads later went 6.57 on a 10.8-1 408 with 4.10 gears on pump 93.
