main caps should be ok have run many two bolt blocks but if you ars going nuts with the spray then you may want to up grade to a bettter cap or stud s or both . you can run the milodon tray or the moroso if you use Arp studs for the tray you may need to cut about a 1/2 inch off the top of two that are close the the front # 3 cap they will hold up the pan off the block or wear two holes in the pan from the studs . i have a nice roller about the spec s as that. if you want a good use roller cam?
