Ported Edelbrock versus W2 out of the box !
Quench dome piston for use with open chamber style heads:
The little dome fits into the open quench pad area of the heads.
So, there needs to be some planning involved so you end up with the little dome being within .040-.045 from the quench area of the head at tdc when assembled.
Getting the quench area of the heads equalized, and the correct depth, with the chambers at the correct finished volume for the desired final CR is usually the biggest challenge when going about it this way.
Much simpler with flat tops or inverted domes and closed chamber heads.
