I don't have numbers to back these suggestions, but I gotta believe the Indy EZ heads flow about as well as any standard port window designs. If you really want a tunnel ram, I've read in the past that the Weiand Hi-Ram is a pretty good piece equimpment, with the M1 tunnel ram being right there.

OOTB flows from the same flowbench for the (1) early Stealth, (2) late Stealth, (3) RPM, (4) Indy EZ
............(1)...........(2)..........(3)...........(4)
.100........66............73...........74............66
.200.......142...........141.........148..........127
.300.......209...........214.........209..........181
.400.......240...........245.........254..........232
.500.......255...........262.........276..........272
.600.......267...........276.........287..........299
.700.......268...........281.........291..........315
Even with the Indy's larger 2.19" intake valve vs the others 2.14" valve, there is no OOTB advantage to the Indy EZ until you get over .500" lift. In fact, if you look, they even don't flow as good up to .400" lift.
Keep in mind that the Stealth and the Edelbrock RPM can be hand ported to 340+ cfm and the EZ can be ported to 360+ cfm. In order to do so, it is generally required to open the ports to Max Wedge height.
Mid 330 cfm flows can be had, from the RPM and Stealth, with a stock intake port window.

Coupla years ago when I was buying Stealths, they were not hand blending the seats into the aluminum bowls like the last four sets I have received. On the later Stealths it appears they are trying to emulate the blending that Edelbrock has been doing on the RPM heads.
