Default Fast intake Bolt Question

I purchased a used fast 90 setup.

Its missing the valley cover bolts, and the bolts to mount it to the engine.


1. Ive read where people have grinded them down- I have a bench grinder and honestly I could have them all grinded down before I could even get to the neearest Hardware store 15 minutes away.

2. If I cant grind them Where can i find similar valley cover bolts locally?

3. What are the thread and length and thread of the bolts to bolt the head down on the intake?

3. im considering the fast manifold bolt kit from thunder racing for 25.00 Will this include every bolt I need or will I still be missing stuff?


Also concerning the Rear MAP location, ive heard people say the map sensor leaked? Is has anyone done anything to correct that?

Go to www.boltdepot.com and order this.
#6658 - Metric socket button head screws, Stainless A-2 (18-8), 8mm x 1.25 x 30mm
Thats the size that I used on a custom valley cover I used to have.

You can get them there, if you can find out what size they are.

Just order the kit from Thunder racing. It has every thing needed for install. Call them first to make sure it's in stock.

I ordered the 27 dollar kit which includes everything but the bolts to hold it to the motor.

Its 75 bucks for the complete stainless kit... No thanks on that
