I am in the process of putting
I am in the process of putting new exhaust manifolds on my cs280 "Chevy 409". The old manifolds were camel hump style the new ones are generic log style. The engine is at a slight angle higher in the front lower at the fly wheel approximately 1.5 to 2" difference. The old manifolds the raw water in went in the front or the "high" side. The risers did not have a separate fill it just fill up the manifold and out the riser. The new manifolds give me an option to feed the raw water into the low side and then to the risers I have to run a hose to feed the new risers unlike the old. Which will mean feeding the manifold on the low side cloest to the riser and then running a hose to the riser from the high side approximatly 2'.I remember reading that this is better way it helps reduce air pockets. The old ones didn't seem to have a problem worked for years. The question is do I leave well enough alone or change it to the "right" way?
