You can also tell by the date and part number cast into the head (You'll have
to pull off the valve cover). The part numbers are different.

Dear Mr. Tiger,
You may be able to narrow the odds that your buddy has your Holbay head on
his
S2, IF he gave the shop a stock S2 head to begin with.
The spark plus holes on the Holbay head should be recessed pockets, rather
than the cylindrical tubes found on Series I thru late-Series V. Also, the S2
head will have the threaded fitting at the back of the head for the pipe that
feeds water to the inlet manifold. The same area on the Holbay head should be
blanked off completely, with no threaded fitting (like S1-2) or even a large
bolt screw, like on most Series IV-V heads. In that case, your buddy would
probably have no pipe anymore to the now-blocked off water inlet on the
Zenith
manifold, which means he should have known it wasn't his head he picked up.
Hopefully - not the case.

Subject: [Alpines] Holbay head
I have a chane to buy a Holbay head and want to use it on the 1725 Im
ebuilding for my S5. Although I do have a couple of nice Alpines (my opinion
f course) I have more Tiger knowledge,but w/ OD, my\this S5 was a ton of fun
nd it had great hiway speed, except with the 18 wheeler problem, it kept
anting to pass them at a high rate of speed. To bad the speedo cable was
roken in half, I might have slowed down. NEways, is there any problems using
he Holbay head Im unaware of? Im installing a cam reccomended by Jim Ellis. I
ad a relly nice stock head I spent hours porting and then sent out to have a
ro finish it BUT the machine shop says I picked it up- funny I left the
lock. I think my buddies S2 has my head on the engine I sold him, as his
echanic had the engine and head in the same machine shop. If he ever blows a
ead gasket I will know for sure. LOL
hanks ahead of time for any help I may receive and happy Holidays to all.
