2.2 S damaged heads problem
Hello,
The workshop which was working on my 2.2 S heads during changing valve guides damaged the outer housing around the valve guides inside the heads. Two heads has been damaged. It is hard two find the exact 2.2 S heads for sale at the moment. Are they maybe interchangeable with other heads for different engine displacement? Maybe after some additional work? Martin |

You can also convert 2.2T heads to MFI and port it to "S" specs. With some welding you can also convert a 74, 2.7 CIS head. The castings are pretty much all the same. We do this conversion all the time. We my even have a couple of 2.4S heads sitting around. I'll have to check.

Does that mean that I should rather go and hunt for any MFI head like late US T or E . I can not find any S heads stamped 911.104.308.0R at the moment.

How were the heads damaged? The valve guide boss split inside the port from aggressive installation of valve guides?

Yes, I have valve guide split inside the port. The piece of housing around the valve guide fell off. I assume that kind of damage eliminates these particular heads?

They can be repaired. But I highly recommend you find a shop that is competent in that repair and replacing guides.

Sent you a DM. Send all 6 heads to Bill at XCH and call it a day.

Sorry you had this issue. Shops not practiced in dealing with 911 heads can damage them. There are a number of good shops the can properly service/repair Porsche heads. The local machine shop isn't necessarily one of them unfortunately.
