What is the difference between the RS/LS/GS and the GSR head? Is there any? And can you put a Header for 94+ integra on a 90-93? It's still and B series

Easiest way is to seach instead of waiting for replies. There are many topics like this.

Theres a header im looking at and it says for the RS/LS/GS but im not sure if it will fit right.

Do you have a GSR? If so then you need to get a header for a GSR no they will not fit. The LS/GS/RS header will bolt up to the head on the GSR but it will not fit the exhaust under the motor.

Its a frankenstein motor. its got a b20 block and a b18 head. the headers and meant for a b18 so i figured it would fit.

whtteg, so if you took a header for a GSR, from any year, it would fit to the head, but the part that connects the header to the exhust wouldnt fit, is that what you were saying?

Exactly what he is saying

Ok, soooo... if i got some 95+ headers and put them on my 93 head, and used the part that connects the header to the exhast from my previece set of headers, that would work? i had a set of 93 DC Sport 4-2-1's that broke, but the part that connects the header to the exhast still is in fine condition. i want to do this, because on ebay there are like no headers for 93 gsr's.

I dont think it will work

Need to custom make one though just buy one for your specific model
