I just picked up a set of twin valve springs from SWR Motorsport for $104. The invoice doesn't have a part number, but I'm sure if you call them on 02-4577-2400, they can supply & mail them to you. I'm using them in a H89 head with an Arthur Johnson AJS35S cam in an A15. Should do the job.

Factory dual springs are good for about 7000 rpm. Specs are at Valve Springs

* 13203-H2300 SPRING-valve, outer
* 13203-H2301 SPRING-valve, inner
* 13205-H2300 SEAT-valve spring

Tomei or Isky and most after market duals are good for about 9000 rpm.
