Louis , is there space for everything to fit as is , meaning to ask if the additional space you need is to get access to get the bolt into the hole
or is there not enough room for both flanges to mate , regardless of the bolt
would a bolt with a thinner head profile get it together ?
- if you bolted the tube to the flange at the headder , then installed both the headder and intake onto the head would it fit ?
if that last suggestion comes close to fitting , could you get away with grinding a little off the head of the bolt once the tube is attached to the headder (but before it all goes onto the head
or would a bolt with a head that looks like this help ?
please note I'm not posting a bolt size or thread referance , simply a bolt type
- you would have to select the correct size and thread from the list for your project , if it's there
IF the tube was installed , would you still have access to all the other bolts for instalation and removal of the headder and intake ?
IF so , I'd consider having the two flanges welded together and forget about bolting them together
if the two flanges were welded together you would possibly be able to grind off anything needed for fitment as you would no longer need the provisions for the bolts
and you would also eliminate any chance of an exhaust leak happening at the flanges which might be a lot of trouble to fix once in the car
and once together I'd consider supporting the other end of that tube so that you don't develop a crack somewhere from vibration and stress
a strap of metal with a hole in one end that could be bolted down anywhere and the other end tac welded to the tube
