Intake Leak

Ok, here's a test I just did when installing my intake last week. My heads are cut way down to like 64cc & ported out so I feel your pain on this. I clean everything up and then bolt the intake to one head without a gasket. Now look at the gap on the other side. Use feeler gauges to measure top & bottom of the front and back if possible. This will give you an accurate idea of how thick the gaskets need to be & whether your faces line up. Then take and set the intake down dry with intake gaskets as mentioned above. Check fit, where the bolts line up, ect.

One note: we all have the same approx sealing area below the ports on our old ported iron head motors so it should seal up without any welding if the intake faces do align with the head faces.
