that is confirmed will work for on-head engine work? I've had schrick cams sitting in my garage for the last year that I may finally get around to installing in the near future. While I'm in there I plan on changing the retainers, and I figure I'll give the job a shot while the head is still on the engine.

I haven't bought a valve spring compressor yet thought b/c this seems to be a job only few will consider doing and I'm not sure if some of the tools sold will be effective in doing this job on our cars.

If anyone knows for sure of one that will work, or has an old VPD style one they'd sell/rent me, please let me know.
