2.0 heads for sale

Are those T4 or T2? Price?

Bart Bervoets

T4??? What T4 uses 2.0 aircooled heads?

Question should be: Are they 76-78 oval port heads? Or are they 79 ONLY square port heads? Or are they 80-83.5 Vanagon heads?

A lot of people believe the 79 bus heads are the same as 80 up Vanagon heads, but NO, they are NOT.

The Vanagon heads are part numbers 071-101-371A for the left and 071-101-371B for the right. They are square port with 37.5 intakes and 33 exhausts.

The 79 ONLY heads look just like the Vanagon heads, with square exhaust ports, but the intake valves are bigger. And the part numbers are totally different: 029-101-371A for the left and 029-101-371B for the right. The intakes are 39mm and the exhausts are 33mm. SAME valve size as the 1700 heads.

The list below is from

[If anyone wants pics of the 79 ONLY heads, I can send them]

Karl, that is the first time someone has actually discribed the true differences of 2.0 VW heads to me. Thank you, I own a Vanagon with the 2.0 heads, now I know what to buy in the future.

best offer.

valves look good seats look fine.

1 head is missing 3 exhaust studs (NOT stripped) spark plug holes not stripped a few dings in the top of the heads, not near valves or mating surface

So the difference between the AC Vanagon heads and the '79 only heads, to my understanding is that the Vanaogn heads have smaller intake valves for better mixing of the fuel (injector heads) with higher velocity airflow partially to compensate for shorter intake runners (?) and to provide for better low end torque. All the FI heads had smaller intake valves than the carb counterparts. The other diff on the Vanagon heads is that if yer gonna use it on a '79 you need to drill and tap a sport for the head temp sensor to screw into on the forward end of the left head. At least that's my understanding of it all... Could be wrong but I don't think so. -BaH

BTW, Karl, most references to "T4" around these parts are actually referring to the "T4" style engines as used in the later busses. It gets confusing whether somebody is referring to a T4 as a T4 or 914 or a T4 as a pancake engine in a bus - which even if one could read their mind it would still be confusing - can't read a blank page, y'know!

square port heads? Or are

heads, but NO, they are NOT.

071-101-371B for the right. They

ports, but the intake valves

the left and 029-101-371B

size as the 1700 heads.

Vanagon heads still have the same temp sensor forward of #3 intake port, same as

2.0 bus heads.

That is the difference between 029A and 029B for 79 and 071A and 071B for Vanagon. A is left for having the temp sensor hole.

You use two A heads on an engine, just not 2 B's. Otherwise you would need to drill and tap the sensor hole in the tin screw hole.

As far as I know, all the replacement aftermarket AMC Spanish heads are A or universal heads. They all come with the sensor hole.
