I am building a delSol for autocross (Solo2) competition in EP, and as such, I need to convert back to the B16 (it currently has a B18C1 that I'm getting rid of). I have a Darten-sleeved block, but I need a cylinder head. It does not have to be complete, as I am most likely going to replace the valves/springs/retainers/cam/etc. I would prefer a B16A3, but may consider others. I can NOT use a JDM head, per my rules. Thanks.
