I am in the final stages of a head gasket job on my 85 Veloce. The head has been rebuilt and machined flat, etc. Looks beautiful!
Cams are turned in slightly inward from their marks as this is supposed to provide a slight increase in performance...looking forward to that.
The Alfa expert that remanufactured the head also suggested I install a "baffle plate" in the exhaust side of the block. The purpose of this block plate is to simulate the older block configurations whereas there were channels within the casting that directed positive flow onto each cyl. sleeve.
With US emissions, etc., the newer blocks elimnated that dedicated flow technique and opened up the casting channels to provide more of an indirect flow to cool the top end of the engine. It is said that this indirect flow allowed for increased operating temperatures and better emmission numbers (lower).
Anyway, this plate simply drops in to the exhast side of the block, settles in just below the bloc-to-head surface so as not to obstruct the head gasket seating, and has a (4) 1/4" holes to "squirt" positive flow water onto teach cylinder.
Has anyone used this baffle plate without success? Just thinking or hoping for some positive/negative feedback BEFORE I reinstall the newly refurbed head.
I have attached some pics of the plate installed. As you can seee, the plate is "dimpled" with pliers towards each head bolt so the plate is "pushed back" against the engine block and forms channels.
Looking for your thoughts and experience on this one!
Thanks in Advance,
Joe
