Gasket match- worth it??

Gasket matching IMO is easier and more consistent. That's what I do.
1. Make sure the intake fits properly. You want the final machining all taken care of before you start.
2. Use the gasket you will use on final assembly. For LA mopars with LA or Magnum heads I like the Mr. Gasket Ultraseals.
3. Use Dykem/Prussian Blue or similar marking compound and "paint" the intake flange (head and intake).
4. align the gasket with the intake bolt holes and tape in place or bolt lightly in place (without compresing the gasket...)
5. Scribe around the inside of each port opening.
6. Remove the gasket, leaving the scribed line in the marking compound.
7. Remove material at the opening to the scribed lines. Do not go beyond the lines!
8. Blend the new opening back 1/2-1" into the port and smooth any transitions/corners.
