OK, to further muddy the water up.=C2=A0 I measured the diameter and overal=
l length of two different tappets according to the original service manual.=
(reprint)=C2=A0 The diameter is spot on for both tappets.=C2=A0 The follow=
er with the four holes has the correct overall length.=C2=A0 The three hole=
tappet is taller, but the bottom of the pocket where the pushrod seats is =
recessed further in=C2=A0 matching the height of the four hole tappet seat.=
=C2=A0 So now they both will work?=C2=A0 If that is the case I'm leaning to=
ward the four hole version for two reasons.=C2=A0 One, it has the correct o=
verall length.=C2=A0 Two, oil will flow back out the tappet back to the pan=
better.=C2=A0 Less weight going up and down too.=C2=A0 Am I going in the r=
ight direction here?=C2=A0 Anyone have the dimensions for the 6 cylinder ta=
ppets?

Mike,
=C2=A0=C2=A0=C2=A0Yeah, don't know what to say. I have this style in my car=
, all eight of them. Are they correct? Who knows? As much of the work done =
to this car before I got it, I have no idea is they are correct or not. I'm=
going to use them as they are all the same and the car did run with them, =
so once I'm finished, I'll see if it still runs and hopefully, runs better =
than it did.
=C2=A0=C2=A0=C2=A0Again, good luck~

That parallax view of the camera lens makes the measurement look off, but i=
