Headgasket

[tnkhang]

I guys I need a little bit a help here first time doing my head gasket replacement on my evo9 And I was wondering if there's a way to get away with Bypassing around the complete timing belt removal & all that as the timing was replaced by the previous owner about 15k miles ago. Would I still have to perform the complete timing belt removal in order to take off the head or could I get around it by it simpily being off the cams only? Some insight would help. Thanks
