We ended up getting a kit with an Eagle Crankshaft, Eagle rods, KB forged aluminum pistons,
and Clevite bearings. Then began the selection of other components.
My husband decided on Ford Racing GT-40 X305 aluminum cylinder heads. They have 58cc combustion
chambers, 1.94" intake valves, and 1.54" exhaust valves. Even with original GT-40 valve sizes these heads flow more than either
GT-40P or GT-40Y heads in original form. The X305's have 178cc intake ports and 62cc exhaust ports. This will provide
additional flow while also keeping the velocity up which is what I want for maximum torque.
When the heads arrived my husband deburred all the sharp edges around the port openings, the
combustion chambers, and spark plug holes.
