Two dots, not one, cast into the head, valve spring cups cast into the heads, and treaded, not pressed in, rocker arm studs. Those are the easy ways of telling at a glance.

Also on the corners just outside the valve cover rail you should see a 19, 20 or 21 cast into the head (sometimes even on date matched pair one head will have a 19 while the other while have a 20). Watch out for service replacements hipo heads which have a C8ZE cast into the head-these are hipo heads, but are not period correct and command less $ than the 63-67 heads.

Joe,

Let me know if you want detailed pics of mine so that you can tell for sure. I have had them done by powerheads, but the pics I have are from before the porting & combustion chamber work.

Wow, you really missed out on quite a deal if that was the case. I have over $1700 in my hipo heads right now just for the headwork and valvetrain components. Luckily mine came with the car, otherwise I would have had to scream. The older our cars get, the more expensive the hipo stuff gets. Hell, it cost me $275 just for the larger ps pump pulley that the hipo used instead of the smaller regular 289. But I digress, le me know what parts you need and I may be able to help you find them reasonably priced.

The HP head is easy to spot. There is a retainer wall around the base of the spring. No other head had this.

Was not aware they were available with power steering.... Was that a dealer installed item ?

Was that larger pulley for an Eaton pump or a Ford pump? I bought an Eaton pump to do my non power to power steering upgrade and it had a larger pulley than the stock pulley already on it. I used the stock pulley that I already had. What would putting a larger pulley do besides reduce the RPMs that the pump turned?

The reduced pulley RPM would save the alternator (and power steering pump, etc.) from extra wear due to high RPMS that the hipo could turn.

You can see the factory K code power steering pulley here. Available only in 67. Very large pulley.

Extremely late on this subject but my engine is a HiPo according to the cast numbers but the heads don't appear to be correct. Did Ford stop making the HiPo heads with the two dots and screwed in rocker studs later in their production?

No Hipos were ever push in rocker studs. If they are not threaded, they are not right. How about the valve spring pockets like in the pics?

I can't believe how old this post is.......
Anyway......There are a few variations but the numbers on the front bolt boss
better be 19, 20, 21 to be hipo 289.
Contrary to popular belief, the 289HP heads are not the only SBF heads to have
cast-in pockets for the springs. The C6FE also does. Definitely not a production
piece but cast-in pockets non-the-less. They were technically referred to as
289HD by the foundry folks.
Here's a photo that separates the BS from fact.....
