Just curious and not trying to put you on the spot, how much of a cost increase over the pre-assembled heads would this add?

many time s it.s less as i buy bluk valve .s springs and the valve seal .valve locks .head companys that sell heads do much the same but much more then a shop like me . many times they build head s set to bolt on. they are going to come apart if i doing the engine so it can be two steps back. or more if they use a cheap tin stamped spring locator and lets say a stock heavy retainer on a solid roller cam setup and a lower spring rate then price as built out of the box is no deal.then it is not so hot of a deal on the big stuff there springs like PSI or Pac that i may use . less you buy the preped springs out of the box they all need some work to keep spring from cutting in and making junk out of retainers
