I need help in figuring out if all B series head fit each other. Im about to buy a 98 LS head to put on my 92. Does any one know what are interchangeable on my motor besides B16a's.

 

yes, its a little tight, but it can be done.

 

a little tight but fit.. cool

 

Are you asking for other interchangable heads? You can use any PR4 head, thats all B18A, B18B, B20B, and B20Z heads. Just be sure to use your stock OBD1 electronic components on it.

P72 (GS-R) and PR3 (B16 and Type R) heads require a little machine work to fit. They are not a direct swap.

 

Thanks alot, i guess ill go with the B18a or B20. but its hard to find a B20
