Head part #???

[Chris181Westy]

I just bought some heads, they were taken off of a 1.7 914 engine, but the part number is 022.101.372. with no letter at the end. On the type four secrets head reference page it says that 022.101.372G heads are 2.0 heads. But these heads do not have a G at the end of the part number and these heads were for sure fitted to 90mm cylinders. I can not find any info on heads with the 022.101.372 part number. Does anyone know if these heads were fitted on 1.7 914s? If not what car did they come on? I know that the 1.7 914 heads HAM inc. was talking had a 021.101.371Q part number. I am confused please help!

Sounds like an 1800 head. Do you have pics of the chambers?

[Chris181Westy]

I will take some pics of the chambers and post them tomorrow. Thanks for the help! Do you think it would be a 914 1800 head or a bus 1800 head?

Sounds like a 411/412 heads... All I know is what the chambers look like by heart....

[Chris181Westy]

I bought them because I thought they were going to be 1.7 914 heads. I got them for $80. For that price do you think they are worth keeping? Even though they are not the 914 heads I thought I was getting? I could return them to the person I bought them from, but if they are still worth $80 I will keep them. They do not have any cracks and look to be in good shape.

I'm not sure there's alot of difference in 411/412 heads versus 914 1.7 heads. (correct me if I'm wrong)

From what I heard, and read, they both have the smallest of everything. Ports, valves, and chambers, but they are a good starting point for high performance because they are beefy, and handle high compression pretty well.

Check out Tuna-can's site, and see which chamber it looks like. 1.7 has the little "cresent moon" in the squish band for the 1.7's domed pistons.

Chris181Westy your 022.101.372. heads are off a bus. They don't have vent tubes in the rocker chamber, (914 'Q' heads do). The exhaust ports on everyone of these I've seen was tapped for smog tubes. To the best of my knowledge there are three 1.7l castings. The 'Q', 'J', and the 372. When modiying the exhaust ports on 372's (and any others that had smog tubes) I weld the opening shut before installing new seats. If seats are not going to be installed I plug them with a sockethead pipe plug.

Ham,

What is your work number? Need to ask you some questions and advise for some head work. I want to get the full potential of my stock 1.7 914 heads on a stock engine and 40 Dells. I am at work right now so if you want, you can email me at my work address: Thanks!

I have a pair of these heads with the '372 part number also. The PO took them off a 914. They have no vent tubes, no smog air injection tubes, chambers identical to my '371Q heads and a factory VW temperature sensor. I think that means they were for fuel injection. No 1700 bus engines were FI so these must be 411 or 914. Why can't they be 914 heads?

Why would it matter if they are Porsche heads or VW heads? The 1.7 porsche and the 1.7 411/412 were 100% identical. Made in the same factory, in the same molds and on the same production line. Ray

First off let me say that Ray Is partially correct about all 1.7 heads being identical. They all have the same size ports, valves and chambers. Components all bolt up the same. The differences are not obvious to the untrained eye. (Except for the breather tube in the 914 'Q' head). Here's how to spot the beefier castings.
Position a head with the ex. side down so the spark plugs are pointing at you. In this position you can look down between the fins. Place a finger on the lower, far right head nut boss. There are five fins between this boss and the intake surface. Look back through these fins. The beefier heads ('Q's' for ex.) have a great deal of extra aluminum in this area that rises towards you when viewed in this position. In lighter castings this area slopes away. The other side of that is the exhaust port. This extra material helps draw heat away from the exhaust valve. This is helpful to stock engines, critical for high-performance, particularly when the exhaust port is "hogged out". This outcropping of aluminum shows up on some 1.8's of the same casting # as well as 2.0l 914's of the same #.

Since my specialty is heads, and I don't pull the heads it has been difficult to confirm exactly which castings were on specific models. I know some, but I still rely on my customers for much of this info. Problem is these engines are old enough and interchangeable enough that even that info. can be misleading.
Just because you don't have one of the beefier castings doesn't mean you have a piece of junk. I have seen many high-performance street engines do fine with the lighter castings. I point out the differences because they exist. And given the choice I want as much meat in this area as I can get on high output engines, especially with modified ports and sustained high RPM's. Racers take note.

Damn..... I never even knew that!

[raygreenwood]

Didn't know that either..Thanks! ray

That educational information is even better when you get it first hand from Len himself at his shop. I saw the heads compared side by side. Unfortunately mine were not the beefy type , but they will work for my application. Great info, thanks Len.

You're more than welcome. Glad to help!
