GSR and B16 head combo question

By 93hatcheg
- Sat Jul 31, 2010 6:12 pm #206926 Ok ill keep it short and simple. Will the internals of a B16 head swap over to a GSR head. Such as the cam hold downs and valves and everything. We found a good deal on a bare GSR head and have a full B16 head. Thanks

However needing to have the journals line bored to match the cams is not needed at all$ I have swapped gsr cams into b16 heads with no modifications plenty Of times. Correct me if I misunderstood what you were saying but I understand correctly I believe that to be incorrect. I appreciate the help

cam caps are made specific to a head. but can but honed to fit to another.

So the journals of the b16 cam caps are different size than the journals of the gsr head is what I'm understanding? Correct? Anywho I trust you guys . This just leads me to a new question... If the journals of the heads are different how are the cams awapped between the heads with no modifications?

- Sun Aug 01, 2010 10:47 pm #207041 i dont think the journals are different but when they make the heads from the cast. they are made just for that head. like you cant use b16 cam caps on another b16 head with out getting it line honed. and etc..
