headers or manifolds for 4 door 318 valiant

we had a 73,4dr,318,valiant for years.was my wifes daily driver.it had a mild cam and 4bbl as well.we live in the stix an got alot of crappy roads so i kept the manifolds on it for ground clearance.the cheap headers are a pain to install,and the drivers side hangs low,it can get crushed very easy.our valiant ran well with manifolds and small duals.if its a daily driver,and the cam is pretty mild,id keep the manifolds.
