Hey Tech.

I have purchased a comp cams H270 (PART #12-211-2) and
Comp 981 springs and have borrowed the cutter to take the guide down to .660 dia for the spring.

My question now is what valve seals do I use?

I plan on using the original retainers and locks. ( can I do this? look like it should work!) I am using the original rail rockers.
By the way, I believe these haeds are factory rebuilt heads and they have .357 dia. valve stems so I think they just put oversize valves in them at rebuild. ( I had to make a larger arbour!)
Thanks
Brad
