OUR ONLINE CHECKOUT is CLOSED and we are NOT accepting any NEW orders at this time.

We are still fulfilling and shipping previously submitted and/or delayed order requests (as product availability allows) UNTIL NOVEMBER 15th 2022.

But after November 15th, all still pending backordered unshipped items will be automatically CANCELLED **(except for any special ordered drop-shipped or made/machined-to-order items).

Our ability to respond to emails is greatly hampered by being under-staffed during this downsize transition time. But we continue to endeavor to answer email inquiries as best we can. And we will continue responding to emails through until early March 2023 because we are wholly committed to resolving any other issues that may arise from previous sales. It is still UNCERTAIN, but we may re-open a substantially downsized version of our store again in the Spring of 2023.

We sincerely appreciate your patience, understanding during this period of restructuring and/or closing. And a huge thank you to all of you whose support and loyalty we have been the beneficiary of over the 23 years that we have worked diligently to support the information and parts needs of the aircooled VW community!

CB Performance 044 CNC Round Port Cylinder Heads, 40 X 35mm Valves, 85.5, 92, and 94mm Bore, PAIR are designed for small to medium size engines, and are based on the same high quality 044 Castings as other 044s! CNC porting is perfect from head to head! These heads focus on air speed in the ports instead of pure flow bench #s! Higher air speed means more power!

This is a fantastic head for smaller and milder engines, including heavier busses, type 3s, and THINGs. Compared to our ACN "L Series" of head, this Round-Port is around an L4 (which we do not make). So it's a great choice for guys where the L5 is a little too much. This head is good for around 140hp, if you have the rest of the engine to back it up!

The combustion chamber is 55cc for the Stock Bore Size (85.5mm) and 61cc for the 92mm and 94mm bore. So be sure to do the math on what CCs you need to get the compression to match your cam and application, you don't want to wind up with 6.5:1 compression and a huge cam, the engine will be a pig!

We strongly recommend that you have an exhaust in the 1 1/2 or 1 5/8" primary size to utilize the flow capability of these heads! Failure to heed this advice can result in difficult (IMPOSSIBLE) tuning issues, and likely cylinder head overheating. It also won't make the power you want!

With these heads we recommend valve lifts in the .450-.500" range, which is where they will perform at their best. You don't have to worry about coil bind, they will lift over .900" at the valve! These heads have 168lbs of spring pressure on the seat, 1.500" installed height of valve spring, and 324lbs of spring pressure at .520" lift.
