I am getting ready to order a high compression
head for my 26. Has anyone ordered one from
Harlon Zajicek, that advertises in "The Vintage
Ford"? What is the difference in his heads verses
anyone elses? Any help would be thankful.
Ed

I recieved one from Harlon and excellent service. I am in the process of installing it now. Looking forward to the extra HP.

Ed,

I bought directly from Harlon, Great service, less money, great support. Have run the head for about 5 hours now and love the improvement.

I would highly reccomend both the head and Harlon.

Greetings Ed, I tried to order one from Harlon but couldn't seem to get a hold of him. I ended up ordering one from one of the main suppliers and they matched his price of $310.00 plus 15.00 shipping. It saved me about $50.00....... it never hurts to ask a supplier to price match their competitors.

I likewise bought from Harlon. I agree with the great service and support. His head is the best thing you can do to make an easy driving T.
Noel

Ed -- Check out research on the Z head and others done by the Tulsa Club's members.

Well I thought that link would take you directly to the page about heads. I just tried it and got the Tulsa club's home page. From there, click on "Technical", then "Accessory Heads".

Just received my Z head from Harlon last week. Sent him a check and I had it no time. Pulled the original head and this afternoon I'll be putting the Z on.

I noticed on the Tulsa website they said the "Z" head looks like the original except for the "Z". Does the Harlon head included the Ford script and Made in USA on it?

Yes it does. It also has Z at the water outlet.

Many originals have the Z also. The main difference (other than performance) from an original is that a magnet won't stick once you paint it black.

Mine may have well been an anomaly, but the interior surfaces were rough as from the mold/casting. This should have been polished out before installation, but the man who installed it for me failed to do so, and only told me about it after the fact. Sometime in my lifetime I will remove it and do that. I have zero complaints about the head per se, it made a significant difference for the better in performance, and I like the sound ! I would really look at the head when you get it though and see if it needs to be polished out, I do know that a head will collect carbon in this area if left rough, this comes from a long line of flat head Ford V-8's way back when. Just my .02, your mileage may vary.

Want to say thanks for all the input.
I put a check in the mail to Harlon.
Looking forward to getting the head.
I'll check the interior over.
Planning on using copper gasket?
Ed

Got the head yesterday. Fast service, no problems.
I do have a couple of questions.
The interior finish is not polished, finish is
as cast. What is the opinion should I polish
this out? Will I get better performance? Is there a chance of screwing something up? One other
question Snyders sells what they call a "Head Saver" is this worth buying, does it work?

Ed,
I run a Z head on my 22 and my 26. Both engines use aluminum pistons of two different brands.

There was .035 clearance on the 22, the head was polished up and has ran great for several years.

When I checked the squish clearance around the piston on the 26 it was inadequate. A router was used to increase the clearance to .035 with the gasket on. It took about .060 on one and four and about half that on two and three. A four inch paddle sander polished up the machine marks quickly.
