Just wondering if a JRSC made for a b16 will fit on a jdm b18c type R motor?? The way I see it, the GSR and LS b series heads are different. The b16 and b18c, and c5 heads are interchangeable. correct? I'm planning on running this JRSC on a stock jdm b18c with a thicker head gasket, 440s, and Hondata...any advice?

 

i have a JDM GSR and its a B18C with a JRSC foir a GSR. The type-r and b16 heads are the same for intake manifolds. If you have a jdm engine make sure you know which one it is.
