The only heads allowed are production Ford cast iron heads. This includes 289, E7TE, 351W, GT-40 and GT-40P (excuse me if I forgot any of the less popular production heads). They CANNOT be ported. They can be milled for compression, have a nice multi-angle valve job and can be gasket matched 1" in from the gasket surface. The same is true of the intake. Permissible intakes are the stock unit, Cobra, Explorer and GT-40. Limitations on a carburated setup are similar.
As far as safety goes, you'll need a Snell 95 helmet and a driveshaft safety loop if you're at 13.99 or running on pure slicks.
BTW: Loose the 3.55's go for 4.10's if you're going to be serious about competing in T/S. You'll love them and they'll give you a tons better 60'.
