    There are, of course, two Top Dead Centers in every cycle, but in answer to the question I think you are asking, yes, any time a manual or procedure tells you to reference something to TDC, it always will mean compression TDC for cylinder #1, unless something very specific says otherwise.

    Of course while the timing chain is removed, any TDC of the crank is as good as any other, and once you install the chain with the crank at a #1 and #4 TDC and the cams in the proper #1 compression position, well, you've just made that be #1 compression TDC.
