Do you have to use "special" headers with gt40p? I'm deterred by this and goin straight for TFS top end because I have $1,000 in my exhaust already. What about gt40? I already have a 93 Cobra upper and lower sittin in the garage... Not tryin to invade your thread, and any help is appreciated!

You don't have to use the P specific headers but they make life a whole lot easier. I'm using BBK shorties with mine and have to unbolt the driver side header to change the #7 spark plug. Standard GT40 heads would work without a problem.

I installed new ford racing roller lifters when I did my swap. Used the stock pushrods and factory rockers.

This might be a dumb question but could I use stock push rods with 1.6 roller rockers and duel valve springs? I'm just worried about all my parts meshing together right when I put it all back together

If they are the right length you possibly could. You will need a pushrod length checker to determine what length you would need.
