thinking of going to the longtubes with the gt40p's. What are the correct ones to get?

I just installed MAC 1-5/8" longtubes on mine a few weekends ago and they fit great. I had BBK shorties on there before that didnt fit too bad, but the MACs are 10times better.

#4 sparkplug is the only one that is fairly close to the header, so I just put one of those heat protectant boots on that plug wire. Also, to get that plug out, I have to use a 3/4" wrench on the end of the spark plug socket(the part with the hex end). No big deal though. Better than removing the whole header like with the BBK's.

theres pictures of them on my website in the pictures page if ya wanna check it out

I've also heard the BBK longtubes fit, but I have no personal experience with them.

got them from ebay for $143, just a little scratched, but no dents or dings, and in otherwise very good condition.
