Do the bowl work with corresponding valves like you mentioned. It doesn't require "huge" parts and peices to aquire what you want. Just good combinations. If your ambition to go "big" is where you want to go, Then by all means, go with the Merlins or equal product.
Im confused, not doubting you. Was always told and under the impression to get good streetable power out of 781 heads was not so much the duration but high lift. Never with all the recomendations I have gotten has anyone recomended such low lift as you did....515 is very very mild for a big block no?
