please define "fully assembled heads"

Does the term "Fully assembled Heads" mean I can just pull off my current heads and bolt the new ones on?

Assuming I have gaskets, sealant, and tools.
I don't have the knowledge or background to assemble a set myself.

In the near future I'm thinking of replacing the stock 77 L-82 heads and possibly intake with something else. If this is do able with very basic skills I would rather do it myself. The emission gear has already been removed by a previous owner.

The 'what' I will be replacing them with is still a unknown.

Have them checked by reputable machine shop before you put them on: I know of several sets of "ready to go" heads (including my own) which had seats not completely sealing or other small problems. It is well worth the extra $ to know they are truly ready to run.

That happened in my case also. I had to change them out before installation. Luckily my pre-bought pushrods were OK.

Pretty much means valves and valve springs are allready installed. You might want to check the phrase "works right out of the box"

IMO at least disassemble, lap the valves a little and reassemble. I purchased a set of assembled Darts a few years ago and noticed the locks were just thrown on.
