Heads 2.7 2.4 2.2
I have bought 6 heads 911.104.306.0r stamped 12.69 K1819g, one of them all same type and year, I intended to use them on a 2.7 1977 Cis engine and seller said that the heads war the same for all types.
The heads has right valves dim. And MFI holes, but the dimensjon innside is to small for the 2.7 cyl. I have hard that the clearence for valves and pistons is to small the diameter innside chamber have to be widened, machined, or can I use some special type of pistons ?
On ebay There is often sellers that claim that all There heads are for 2.2-2.4-2.7 engines but is this real ?
