What do I need for intake torque sequence?
Make sure you follow the manufactures instructions for the proper procedures and torque specs if they have specific values as many do. You will need the usual things for the installation, including the intake gaskets, end seals if you desire to use them, possibly thermostat housing gasket and any other small parts along the way.
How big is a small block intake bolt?
Small Block Ford Intake Bolt Torque Specifications 18 Ft/Lbs – Aluminum Heads 22-25 Ft/Lbs – Iron Heads Do the torque in 2 steps, first just hand tight, second with the torque wrench. IF you do have a spec from the manufacturer follow that. Make sure threads in the head are clean and in good shape.
What to know before installing an intake manifold?
Some Common Intake Manifold Installation Tips If you have an old used manifold, before installing it, check for cracks, leaks and the threads in the thermostat housing (often a problem area) and the threads in the bolt for the distributor clamp. You don’t want to find out you have to toss in a Helicoil or other insert while it’s on the car.
What should the torque be on an aluminum intake?
35 Ft/Lbs – Iron Heads The torque spec can be anywhere from 25-35 on Iron heads, but for aluminum I tend to go towards the lower side. IF you do have a spec from the manufacturer follow that. Make sure threads in the head are clean and in good shape.
