Review on Edelbrock EDL 8508 HARDWARE KIT by Omar Gonzales

Ordered this item for an Edelbrock 2105 intake manifold. When it came time to bolt the manifold on, the bolts didn't go into the holes on the cylinder head. To give it a try, I went out and bought a nut that perfectly matched all of the original bolts (3/8 coarse). When I tried putting a nut on the new Edelbrock bolts, it only fit the 3/10 bolts and not the other 7. I sent the bolts back and got a different set. Tried the test nut again and only 4/10 bolts fit. Not sure what's up with Edelbrock, but these screws are not milled/drilled/tightened properly and will not fit.
