W/ long tubes, GT40's will fit the same, P's MAY fit okay. It depends how far out your primaries come before bending down toward the collector.......

+1 otherwise the drivers side plug wires will be burned up in no time. The passenger side always seems to be alright. What about some thumper E7's? http://www.thumperoforangepark.com/

The shoulder on the plug bottoms out before the threads can even start in the hole. I ordered a whole set thinkingI was soo smart. [>:]

so my headers will bolt up??? i thought the whole reason you had to get different headers was because the holes wouldnt line up. ya im thinking about thumper right now. but i found a good deal on a upper,lower and 65mm throttle body so that will probibly come first.

the holes are the same, its the follies with the spark splugs that get ya. maybe some creative denting with the right plugs and wires will work, but i have no personal experience
