Well, I picked up a copy of the July 2003 Muscle Mustangs & Fast Fords and started reading it cover-to-cover. The "Ask Bernie, Yo Ken" column on p. 37 suggests Power Heads or Ford Racing heads as the most direct route to obtaining an additional 80-85 horsepower for a reader's '97 GT.
An article of special note is Richard Holdner's superbly written "Under Pressure" column on p.32. For those planning to install superchargers, he explains the case for first making the car run as well as it can, normally aspirated, which in turn allows you run with LOWER boost pressure, and still achieve the "maximum amount of airflow available from the supercharger." His logic is simple and direct. This has made me reconsider the ported heads option more seriously.
Aftermarket head manufacturers are claiming HP increases of up to 75. I'm just not knowledgable enough about these kinds of products. Who are some of the leading manufacturers? One ad on p. 227 sounds good. It's from a company called "AFR" who claims, "AFR's trademark 3/4" thick deck makes them ideal for nitrous or blower applications."
At about $1,350 a pair, complete with parts, high-flow aftermarket cylinder heads appear to offer a fairly good bang-for-the-buck ratio. How much is a head install likely to cost? What other issues are there to consider with an aftermarket head?
