99 01 5.4 Lincoln Navigator Heads Complete 32 Valve 4v Tumble Port Dohc on 2040-parts.com

1999 - 2001 Lincoln Navigator 5.4L Tumble Port heads. These heads have been checked for cracks and defects and are in good working condition. Heads can be used to convert any Ford modular 2-valve engine into a 4-valve engine.

SPECS:
These heads flow 218 cfm at .500" valve lift (intake). 153 cfm at .500" valve lift (exhaust). Combustion chamber size is to 53cc. The intake port volume is 184cc. This is the same port dimension as the C head, but larger, and there is more material on the head that could be ported if wanted. Many racers use these heads in race engines that are naturally aspirated and forced induction, with great results. Heads can flow 300 cfm on the intake side and 230 cfm on the exhaust side with a good port job. These specs are from Sean Hyland's 4.6 liter Ford Performance Engines book and from Muscle Mustang's and Fast Ford Magazine.

No core charge

Shipping charges are pretty high on these heads because they are heavy (consider 4 camshafts, complete valve-train, 2 head castings, and 2 valve covers) FedEx charges $135, and $20 to make a wooden enclosure. If you know of a way to get the heads shipped to you cheaper, please let me know and we can make it happen.
