Hi all, I am in the process of looking into a rebuild for my 289. Not having either the time or the space needed to do it myself I started calling around and found a shop that will offer a rebuilt with a 7 year/70k warranty. He said they have some hipo heads available and asked if I was interested. This will add $300 or so to the costs. Overall installed cost will be between 1800 and 2300 depending on options I choose.

Question is, what benefits might I get from the hi-po head, is it worth it in your opinion? (kinda wanting it, not sure why...lol)

They are nice to have. The screw in studs are good to have.

You want them for the cool factor!

If the heads are true Hipo heads, with a 19,20,21 cast at the lower left edge where the valve cover flange meets the head, they would be worth $300 just to resell them to a Concours restorer. As far as performance goes, there is not much different if they are stock condition. The screw studs are nice if you plan on pushing your motor to high RPM, this dose allow you some flexibility of adjusting valves. The cast in spring pockets will keep the springs from moving around. But it stops there, chambers and valve size are the same as a stock 289, early. For someone to give you a 7 years warranty on a motor is sounds like it is relatively stock components. If you have the extra bucks, go for it.

Ty Steve and Mike for input.

Steve, yes 'cool' factor . But am not at this time planning other than a mild build. Hence, no real benefit other than cool?

Mike, they offered many components added to the build beyond stock and still offer 7/70. Called around and seems they are trustworthy. I asked about specific list of components, and to mail them to me with copy of guarantee.

So, what I am concluding here, if I read answers right, is that screw in studs are good options, but only if I plan on building it a bit more, and cool factor?

Also valve sizes and chamber sizes are same as early stock 289 heads?

I fail to see the draw, if I concluded correctly for the Hi-po heads.

Cool factor... is cool.. but.. rather spend in other direction if no real benefit?

Thanks for input folks, I appreciate it

Jerry,
I guess I should have asked, if you don't go with the Special heads, what do you get with the rebuild?

Mike, For $2215 They are rebuilding the motor with flat top pistons, hipo head (verified), and a mild RV2 cam. The price includes installation as well as stripping the engine compartment and repainting/detailing. All this comes with the 7/70 warranty.

I have decided to go ahead and get the hipo, what the heck, cool factor wins...

That's a very good price. Look around at different choices for cams. I don't know the specs on the RV2 but there are some pretty decent cams out there that are mild. The Comp Cams 270H comes to mind.

Are those cast pistons? I prefer at least hypereutectic. If you're staying fairly stock, {under 6000} you don't need forged pistons, really.

Like kcode said, aside from the cool factor, you won't really make more power with the Hipos. That said, you made a good choice taking them. It pays to use good hardware. {I much prefer screw-in studs}
