WILL THE BBK LONG TUBES I HAVE ON MY STOCK HEADS FIT WITH THE GT40P HEADS? OR WOULD I HAVE TO PUT DIFFERENT HEADERS ON IT....THANKS

I think those fit with small modifications done to them. I had them before i put on my P heads, but just got P headers to be on the safe side.

I heard you needed different headers for the P heads, but you could always try to modify your current ones.

Call bbk and ask them if yours will work. I have mac long tubes and they told me they'd fit no problem. They did tell me that i'd have to run a 90 degree spark plug boot so i dont melt the boots. Call bbk

i read a great article on the gt40p heads. they tell you all the heads that fit. +1 on the 90 boot cover on spark plug but on the #4 tube you have to slightly kink it to make it not touch the spark plug or something. i'll see if i can find that article and post it later
