360 short block suppliers??

Thanks Terry, I will..just dont rush me...lol. I think there will be a few new posts when I get some time, and dig out the head castings I want to test. I know the lower the angle of the seat the better the transition from on the seat to low lift flow, and the more it's lowered, the more the transition from mid range to high lift is negatively affected. The back cut helps the low lift, without effecting the mid or high negatively. I've just never "gone the full distance" bringing it to the seat margin. Sigh..more to play with...lol. The more I learn , the more I know I dont know yet...lol.
