Hi, I've decided to do an ls/VTEC rebuild and have some questions about the head.  I was kicking around the idea of buying a new bare head ( eBay Motors: Honda B16 VTEC cylinder head BARE..brand NEW!! (item 130220952143 end time May-14-08 19:28:35 PDT)) and installing all the internals.  Only problem is, what type of head is this?  A b16a1? b16a2, ect...?  does it really matter? I don't to be buying internals for a B16a4 and find out that the bare head is really a B16a1.
Thanks in advance.
