Not sure these flowed like stock, anyone know?
The motor has a maggy sc on it so do you guys think I would be better off with a set of l92 or something else?

[QUOTE=JonCR96Z;12899067]I dont think the stock seats will work for anything bigger than 1.57.
But I can have them cut and just blend them in right?
Here's some stock 243s that I just had flowed.
thanks, I guess I did get some gains. but I am still considering new ones. Need to get some cam ideas has well.

you can get 1.60 in them. it is almost to the edge of the seat but it is do able. u might pick up a few more cfm if you open it up just a tad more at the top of the cathederal, where the injector sits.

well I have my whole motor apart (spun a crank bearing) so I am looking at a new cam. As stated earlier, I have to buy new exh valves, springs and retainers for my current 243 heads so while I am at this stage, should I just bolt on a set of L92 heads, I can pick up sets cheap.
