911 Weber Heads 2.2 70-71 Rebuilt

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.

I will be selling the rest of the motor during the week and figure I would offer it here first before going on e-bay. I have also have a engine case, crank, cam tray, rockers, a brand new NOS Mahle P&C set for a 2.2 911S 84MM, excellent 5 speed trans, and a bunch of Porsche bits to sell, so check back for my other posts. Please e-mail or PM me with your questions, Thanks Allan

These are the cracked fin heads, the good heads are perfect, thanks Allan
