LA '340' Edelbrocks

PN 60179 Edelbrock...Website says chamber is milled .060" deep for + deck pistons. My question is has anyone milled these heads to closed chamber for quench? What was the new head cc volume? Is there enough material in the chamber to regain the lost volume? Once milled to closed chamber can I achieve 64-65cc's?

Yes I've milled them to make them closed......

I do not remember chamber volume, has to be in the 55-57 range at least. With radical reshaping of the chamber, yes you could get back to around 63.

I just milled a set of CNC INDYBrock heads to edge of intake seats, after their big 74 CC CNC chamber & they were 62.5 CC at edge of seats.

That is what I wanted to know, thank you.
