Fuel Injection Dual Port Cylinder Head, 35 X 32mm Valves, Chinese, 043-101-355CK is a stock replacement head DP engines. Sold per EACH. Spark Plugs are 14mm x 3/4" reach.Many used heads have a lot of issues that are expensive and difficult to repair, like loose seats, loose valve guides, cracks in the combustion chamber, worn valves and seats, broken and missing cooling fins, etc.
We have been selling these heads for a long time with great success, and use them on the ACN Long Blocks, which are one of the highest regarded engines available anywhere!
These heads are well finished, and have a great 3 angle valve job done to them out of the box. The springs, retainers, keepers, and valve guides are also of a very high quality. We have seen a lot of casting flash problems with the most recent Brazilian and Mexican Dual Port heads, but that is not a problem in these!
These heads can be used on upright engines using 83, 85.5, 87, and 88mm P&Cs. These heads will also work on Type 3 engines (Fastback, Squareback, and Notchback).
Note that these are sold per EACH, you'll need 2 of them to do one engine.
