**600hp sbm block limit? Or is it bs!!**

Yes. Do you know if they will fit on a stock bore block though?
Depends on valve sizes honestly. They should but worst case scenario you have to do a little bit of notching and de-shrouding. My W9s with have 2.15 and 1.6 which on a .030 over 360 I'm guessing it will require what I mentioned. Stock bore may be a little iffy
