If they won't work, you can order nice button head bolts from boltdepot.com and they aren't expensive.

I don't remember exactly, but am thinking they are shorter. Just measure the height of the step on each manifold (where the bolt inserts). The difference will be the difference in bolt length.

Notes: Get some high temp. silicone & put a bead around each head inlet port & each manifold exit port; or just put the a on both sides of the gaskets.
This will ensure no manifold leaks.

Absolutely the best thing you can do for the Weiand, is to put a heat shield/blanket under the intake (between the intake & block). I used a DEI (modified) intake blanket. One could use a header blanket (modified) or even strips of header heat wrap. Anything used to shield the manifold from the blocks' heat will be helpful.

The bolts are shorter definitly and the intake should have come with new bolts. Easy install and if you have any questions you an PM me, i've put it on and taken it off my car too many times for different reasons....

Install is just like any other intake pretty much. The correct bolts for the intake are allen head bolts & they are shorter than the stock bolts. I had a set of paper gaskets cut to fit my ported Lingenfelter intake, but I didn't have the correct fittings in the back of the intake so it had to be removed.

When I put it back on I'm ordering these gaskets from Summit. They are designed to work with Aluminum intakes for LS motors.

I think they're M6x0.75 (might be M6x1.5). Take a bolt from your stock intake w/ you & check the threads w/ a nut @ the store.

umm definatley m6x1x90 you can get them at the hardware store just make sure u use nice big washers as the bolt heads are tiny and dont disperse load

Whoever has this intake on your car, can you post some pictures of it in here? I want to see how it looks installed.

im curious as well as to how this thing performs in comparison to an ls6..im sure it isn't as good as a FAST, but the one im looking at is ported, so perhaps its close..
