You've asked the wrong chap about OHC non rocker heads. This could be a
pain I must admit. If the valves are out of clearence then they do need
to be adjusted. I think you have to shim up or down the cam??? That
way you can only do one valve at a time. Presuming your confident on
both mersurements, you will need to adjust the clearences. I woulent
put it past them to need re-adjusting after the engin has setteled in.
Things like you have re-torqued the cylinder head. You did make shure
that everyting was the same specefied temperature when you measured it.
I expect that if you mersure your compressions, if they are down, then
it's propeble that the valves are at fault. If there not, then I would
look else where. Try a manifold vacume gadge, you can diagnoes alot of
thing, by sticking one of those in your car.
