When the engine fellow reinstalled the head gasket on my rebuilt 261, I noticed the #1 and #6 pistons were at the top of their strokes (besides being new and very, very pretty).

How can I tell if #1 is at TDC or 180 degrees off after I install the lifters, pushrods and rocker arm assembly?

I know you can feel for pressure in #1 spark plug hole while turning it over but is there a way to figure it out by just looking at the pushrod or valve positions?

Thanks!
