will my dc 4-2-1 headers and my greddy cat back exhuast work with a b18c1 block? they are currently on my b16a2

 

yup

 

They won't even know you changed

 

the cat length is different, so you may need a new one/test pipe

 

i didnt no they made headers for a b series i though they only maded a header

 

the header is probably going to be too short and hit the oilpan

That was my concern as well. I think the deck heights are different and they make the length appropiate for both the B16 block and or the B18 block. Also like someone has mentioned, the collector is either shorter or longer between the two. If you're good at fabrication and have some tubing and a welder then that won't be a concern.

 

i know the intake manifold will not interchange from B18C1 to B18C5....doesnt apply to headers?

all b series exhaust flanges are the same
