Do you mean milled .030"?
Cut down to .30 means nothing.

I would most definitely check for PTV with that cam and milled heads, and measure for pushrod length.

Unless you have the valves recessed or use a thicker gasket....

Very unlikely this combo will provide acceptable ptv measurements. Even with stock unmilled heads, the MS3'S PTV has only been described as adequate.
