[Olsen911]

I'm helping a friend to clean the garage after his father past away.

We found a lot of porsche parts, will you help identify these parts and put a value on them.

TX. Tommy.

First, we found 6 pcs. cylinder head with No. 911.104.306.0R all dated 8+69. what are these for.? and what is the value on these.?





They have been laying there in many years, but They look like they have never driven before.

And then we found 6 pcs. cylinder heads with No. R901.104.305.02 all dated 10 +66, is this 911 67S.? and what is the value on these.?





They have been laying there in many years, so there'll be som work on them.

Thx. Tommy

Weber Head as one result from Googling the numbers:

I have a complete set of Weber Heads for sale, part number 911.104.306.0R, machined and rebuilt and ready to use. The heads are off a 1971 2.2 911T with Webers and have 33MM intakes (lightly ported?) and 32MM exhaust ports. Valve sizes are 46MM and 40MM. New springs when rebuilt. I understand that these would make a great core to use for race heads as it could be ported any way you want (more material). The dates are as follows:

12-70, 12-70, 1-71, 1-71, 1-71, and 3/71.

Good news is that they have all been rebuilt and 3 are perfect. Bad news is that the 3-71 has 5 cracked fins, 12-70 has a single small corner chipped off, and one of the 1-71's shows a crack on the fin on the thin area by the spark plug, but the fin is intact. Just wanted to be very clear on condition and will furnish additional pics upon request. Otherwise it would not effect usability. Asking $600 for the complete set plus shipping.
