Looks like solid flat tappet it is. Thanks for the reassurance. About the roller I do like the idea of no break in. I added the cost and it would cost me roughly 2k to go roller vs 5-600 solid lifter.
Jeremiah my thoughts exactly on running pump gas. When i race I will use some 110 but for cruising around I'll try pump fuel with a splash of 110.
I thought there was a chance this could be a more controversial choice, but it appears solid is the clear winner dollar for dollar. There are other areas I can use the money difference that will be better performance wise.
