My stock stroke mild 360 build ;)

Off enough to where I can’t get any but one bolt started.


Bolt holes are too low.
...didn’t wanna have to machine the intake, Or heads, wouldn’t they then be limited to this engine only?

Does this happen often when a block is machined? I thought very little is taken off the deck to where there would be no fitment issues. :0


There is no such thing as one intake fits just one engine. Machine the intake. There probably isn’t another intake that will fit what you have.

If you set the intake manifold on without a gasket and the holes line up, tell the machine shop to get a clean surface on the intake face and THEN take the FULL gasket thickness of whatever gasket you use.

If you set the intake on without a gasket and the holes are not lined up, you take a clean cut, the gasket thickness and how much the hole is off as a percentage of the gasket thickness.

So, let’s say you put the intake on and half the bolt hole is lined up. That’s a clean cut, the gasket thickness and half again the gasket thickness.

So...let’s say your gasket is .040 thick. In the above example of the intake lining up perfectly with NO gasket, you take a clean cut and .040 off the intake.

In the above example of the intake being half a hole high, you take a clean cut, .040 for the gasket and and other .020 because you had half the hole showing.

The last example would be if you set the intake on with THE gasket and you are half a hole off, you take a clean cut and half the gasket thickness, which would be .020 if you use .040 gasket.

EDIT. This happens all the time.
