I know somebody who has a set of .060 Ross pistons, and an older set of prepped stocker heads that you could most likely make a deal for to get you started. You could race that deal with stock lifters, and normal spring pressure as well. Also no EGR valve in the intake.

The best way to attach the headers to the ends of the port is to drill and tap them. Then use a simple stud.

screw in studs is a simple process that anybody can do, don't let that scare you away.

Turning that car into a 77 is alot of time an effort, plus some money. Im not sure that 5c deal is the way to go either. No compression at all. the 72 455 will pour to 9.2 compression. that other deal will be lucky if it makes 8.0

the 71 455 has a very small intake runner. 144cc and at 325 is a dead player

I didn't realize the 72 7M5 deal was 10 hp less than a 66 cast head. What's the deal with that? 10 less hp for peanut plugs?

I got that taken off in 2003. Nobody ran fast with the combo in the modern age at the time. Just played the game. The engine cant run in an F body. The 71 and 73 can be used in an Fbody
