Whats gasket matching!?!?

[Foxfan88]

I assume its just matching the holes to gaskets???
Where on the motor would this need to be done etc....

Trim the gaskets to match the ports, or trim the ports to match the gaskets.

Most gaskets have openings larger than the ports they are meant to cover. If the port has enough metal, you can get increased flow by enlarging the port to the same size as the gasket opening. You will want to do the port on each side of the gasket to get the full effect.

Areas that this is usually done involve air/fuel flow. Intake ports between the upper and lower intakes. Intake-to-heads is another area. Exhaust ports usually need little if any matching.

I would suggest having this done by a professional.

SO if the hole is smaller than the gasket, you port the hole to the gasket?
and you grind the gasket if its too small for the hole??

Yes, you can trim the gasket a little bit or get a bigger gasket.

You got it...

Get a Dremel tool and mark off what you need to trim and do it yourself. Just take your time and be careful when your doing it.
