I should say it says intended for Marine.

no not at all there made were you would use a big cc iron head .they are to big for your marine use if you just have a 030 454 there not to big for a 540 in street use or marine use. if you want a iron head the heads may come with inconel ex valves that would put it in to a marine use or a Nos .. blower or turbo use water or land. there nothing done to the iron head it self to make it only marine that i know of .but there are alum heads that are built for marine use and are coated for salt water . i know of custom merlins in 345 built heads for off shore racing and have custom valves sizes.i just threw out a box of inconel valve out for them. i can not talk about them on a open forum
