GT40's
 

just a few little questions for the sake of comparison. is there any difference in hp gains between the gt40 cobra and gt40P head on a stock 5.0, and also how much of a gain over the stock heads is there for these heads? im just sorta wondering for sake of knowing, thanx.

I would also like some information regaurding this. I want to build on my 88 GT and have fun with it but like most of us im not rich, so this would be a budget way to some heads over the stock 5.0's IF the give HP gains that are worth the money spent on some used cobra heads.
