Need Gasket Info

[Fastest1here]

I have a question that I need to know before I can re-assemble my motor. I just had my cylinder bored and sleeved to a 440 and they decked the top of the cylinder -.020
So my question is, How many thousandths thick is the base gasket on a stock 400ex.

Thanks,

Jim

Will that effect your cam timing??

yeah I heard that it will retard my cam timing by about -1 degree.

Retarding the cam timing will move your powerband up a little bit. I run 4 degrees retarded on my car to increase upper rpm power.
