## Description

Moroso 38400 Intake Bolt for Small Block Chevy

Review: Great Product - Worked Great! Good price!
Review: Outstanding Bolt - The average socket will not work with these. 3/8 socket with the same 12pt pattern must be used. Makes this nice because the average thief doesn't carry this socket. Bolts look amazing as well. I recommend these if you are installing an aluminum manifold because the bolts and the washers are hardened. Just be careful when working with aluminum heads.

Miss the old days when they used to supply the bolts, nuts, and washers with the parts. Now you have to buy them separately. At least they worked.
