DDK - Die Deutschen Klassiker

Hi

Can anyone recommend a good machine shop that is familiar with 912 cylinder heads.
I am thinking of getting the heads to my original engine refurbished.
Machine shops I have contacted locally have no experience of Porsche aircooled heads.

Cheers
Phil

Hi, I’m not sure how different 912 heads are from 911 ones but I’d imagine the basics are pretty much the same.

I used http://www.robwalkerengineering.co.uk for mine, valve guides, skim, valve seats, blast etc

Still going strong so no complaints!

We can help. We have our own machine shop and full-time machinist.

I found this post from Chris Turner agreeing with you viewtopic.php?f=2&t=50092&p=424586&hili ... is#p424586

Angus has a nice setup too (Will his mechanist is ex RedTek) and if that isn't enough recommendations call PRS and ask them to recommend.

I had Andy Prill sort mine.. I am sure he out sorced them but at least he was asking for the right way to have them done..
not cheap! but hey ho what's cheap on a Porsche.. on yes, the road tax
