Are there any numbers stamped into the crown of the piston on number 6? Do
they read anything like +.010", +.020", +.030 etc.? This is a dead
give-away if the motor's been rebuilt. I was surprised when I pulled the
head off my TR6 12 years ago to find that it already had .030 oversized
pistons in it. I ended up rebuilding it anyway and sticking .040 oversized
pistons in there. But, if there are markings like that on the pistons, it
has definitely been rebuilt. If there's not, then it still could have
been... but perhaps just not very thoroughly or there was really no need to
bore and move to an oversized piston.
I think mine had numbers engraved into the rods, too. I don't think that's
an indicator. (done at factory?) I can't think of any other signs to look
for.
