Which bolts go where on TPI runners..... stupid question

I took the TPI apart to polish it, now im puttin it back together and dont remeber which bolts go where for the runners. Theres like 4 long ones and 8 short ones or so. Does anyone have a diagram or somthing that can help me place the bolts in the right holes. Thanks.

the plenum to runner bolts should all be the same size

the runner to intake bolts should be 3 sizes.

2 long

3 short

1 medium (the one you have to get from the opposite side)

at least that's how it is on mine.

ok sounds good, but which bolts go in which holes for the runner to intake, the medium ones for the opposite side but what about the other 5 bolts.

look at the runner itself. should be easy to tell where to use the long ones and short ones from the casting.

it ain't that easy .....I got'm muffed up too ...... but I ended up shiming one with washers......just to drive it .
I spent 2-3 hours takeing them out and switching them back and forth ( on the bottom only ) .....it sucks trying to get them suckers in . But that was my first time takeing it off .....so I learned alot of stuff the hard way

hmm,,,ok

you know where the medium bolts go...

the 2 long ones go between each tube (the short ones obviously wont go all the way thru), the rest go in the rest of the holes.

blue = short

red = long

Are you looking to get in the lower intake to runner bolts, or just the runner to plenum bolts?

The easiest way is to install all the bolts into the runners BEFORE YOU try bolting them on.

Just look at how far the threads extend with the bolts inserted in the bolt holes. Juggle the bolts around until all the bolts have the same thread extension.

Visually, some of the locations on the runners have an extended boss; these call for longer bolts.

These are the two bolts that dont have threads all the way up. There should be two bolts with a gap about 1/4" with no threads on it. Those are the ones that go underneath the plenum. Hopefully you understand what I mean.
