FTI - GT40 Beehive Valve Spring Kit
This special FTI beehive valve spring kit is designed as a direct replacement for stock, single springs used in most GT40 heads. This spring kit is what we use in our dual purpose street/track GT40 iron heads which require a stout valve spring.
Because of the variables in stock cylinder head castings, you must be able to verify fitment and installed heights. This is considered an "easy to do" drop in kit and does not require any machining to the stock spring pockets however, all spring parameters MUST be verified.
