Yup. same heads here in PISS POOR MAG style. I'm at a .600 gross lift and I had about the same as that with the Icon (IC-745) forged piston with you having more lift and my piston being more out of the hole.
I said....that head IS the answer to THE piss poor mag design... That means it is a little better and answers the need for that market..you didn't read that right....
That head is not as big as the LA, not as small as the mag... not as good as a W
I don't know why all, some of these aftermarket companies keep copying/modifying this stuff, rather then copying or bringing back the good AL W-2 or the 5, or make a modified better head from the W base.
