Only W2 tunnelrams i can think of where Holley pro-dominator and MP M1 as has been said before.
Regarding the Edelbrock Tunnelram,i dont think there is enough meat in the runners of that intake to be able to match it to W2heads and if there is, enough i dont think there will be enough to get a nice funnelshape into the whole runner,you would proabably end up with a very straight and even port area from top to bottom,but only one way to find out and that is to measure them. and oh yeah if there is you will also have to drill for the different bolt pattern.
