can anyone help me? I recently acquired an 1985 prelude A18A1/ET2 engine 1.8L  dual sidedrafted carb TEC version. I would like to swap out the head and the carbs that are connected and swap in another honda head with throttle body. Does anyone have any info on which heads will fit and work. I've been told pretty much any V-TEC because it is a TEC engine but if anyone knows any actual engine codes they know work i would apppreciate any help.  

try a b20a1 from a 89-91 si prelude
