Timing belt broke on my 91 Si with a b21a1. Planning on replacing the belt and doing a compression test (probably wishful thinking). If I do need new valves anyone know a good site to get them from? Is there a head swap worth doing on these engines? Was planning on doing body work this winter and engine next, guess those plans changed. I have a 90 Prelude s (2.0 carbed) for a parts car, but I doubt anything off that is usable. Any help would be greatly appreciated, 10 mpg in my truck is getting old quick.

 

rockauto.com for parts. The only thing you could maybe do is a B20A5 intake cam
