Do you need to machine the intake manifold?

Do you need to machine the intake manifold?

Assuming that you’re not a complete idiot and actually recorded this information, it should be no problem. After machining the deck surface of the cylinder head, it is necessary to machine the intake manifold side of the head.

Can a cylinder head be machined for a manifold mismatch?

On engines with the more traditional intake manifold construction, as opposed to those where the intake manifold also serves as the lifter valley cover, the manifold mating surface of the head has to be machined to correct the mismatch.

Why does the intake manifold not mate with the block?

This is as a result of the third mating surface for the intake manifold: the block. Put simply, if the cylinder heads have been machined, the intake manifold may actually contact the block before it can mate with the intake surface of the heads.

Can a resurfacing fixture be used on an intake manifold?

An Intake Manifold Resurfacing Fixture can be configured as a rollover fixture to recut the head side of a sealing surface, then hold the head while being machined for screw in studs and guide plates in one set up. This uses no additional parts or jigs than those supplied with an original fixture purchase.

How do you make plenumstyle intake manifolds work?

To make any plenumstyle intake work, we have to consider the size and efficiency of whatever feeds the plenum in the first place. Next, the entry into the runner has to be optimized by suitably reshaping it. After that, the diameter and length of the runner itself has to be determined for best results.
