If you guys need gaskets, I found out some of them are available through Rock Auto
You need to check for an 86 Prelude 2.0L
If you need A B20A Head gasket, choose the BGA CH8303 head gasket.
This is the one for the B20A. I'm currently using this gasket on my car.
If you need a B20A Oil pan gasket, choose the BGA OP0355
Timing belt is GATES Part # 5211 or KLARIUS/QUINTON HAZELL Part # QTB336
