Go get yourself a copy of the torque specs for the bolts.
Go out to the garage with a pen, paper, metric rule, wrench, torque wrench, sockets, and your thinking cap.
Lay the spacer on top the intake and see what bolts will need modified. ONE AT A TIME, remove them, measure the actual current length, measure the thread pitch, and the diameter of the threads. Document your findings on your paper. You did remember to bring a paper out with you, didn't you?
Now, re-install the bolt, tighten to spec, and move to the next one. Lather, Rinse, Repeat.
When you reach the end of the intake, go back and check that you didn't miss anything. Take note of the head type, and if you will need to provide washers or not. Make notes as needed.
Check around the perimeter of the intake for other bolts or items that you may need to source while at the store...
Now here's the tricky part - take your intake spacer, measure how thick it is... and then measure how thick an intake gasket is as well. Now - add these two measurments and ad to the length of each of the bolts you measured.
Brace yourself, you're about to see where I'm going with this...
TADA! Eureka! You have suddenly found the length of each bolt, as well as the thread pitch and diameter of the bolts! Pace yourself, it is yet early in the modding weekend!!
