I need help on knowing what to do for the cooling system because there's 2 spots for water to come out of the head and I don't know where to connect them. also there are two spots for hoses on the bottom of the exhaust manifold where mine only had one. and I'm also using the carb which is a bn circular carb and intake manifold off the 440 head and I don't know if that's doable or not? if so what should I adjust my screws on it to???
