Ported Indy VS open chamber ported W2

If you use W2, they willl not come close to a closed chamber Indy unless you have quench pad on you pistons. I have aluminum W2 heads and my problem is that I can't change because of the quench pad. I am done with serious racing and would like to put on Edelbrocks but I need to change headers, intake, heads and rockers. Oh yeah, buy different pushrods. Not cost effective for this old fart. My Diamond W2's flow over 300 cfm which I have no use for now. I wish that I could afford to sell them and have some younger racer get the power they can make
