I was going to install these on my GT500 motor but decided to go another route. For sale is a set of brand new Ford GT cylinder heads,COP covers and Cam covers. Everything is new. The heads are bare. Price is $1500.00 plus paypal fees and shipping. When I ship these I will wrap them in plastic wrap mulitple times,lpace them in the box and fill the box full of expandable foam. This is the best way to assure the heads are not damaged during shipping.
