That head looks a lot like the AutoDelta 4-valve head, if memory serves. Not too many were made and I imagine very few survive.
I've seen photos of that type of head being used with turbos with Lucas or early Bosch FI. Allegedly, that type of setup can produce 400 or more HP from a 2L. - Eric H., Marietta, GA ----- "I own 2 Alfa Romeos and both of them run!" 1991 164 base (formerly, John Hertzman's car) - 1976 Spider (awake again after a long, long rest) Non-Alfa: 2009 RX8 R3 -- to be removed from alfa, see http://www.digest.net/bin/digest-subs.cgi or email "unsubscribe alfa" to [email protected]
