Hi Greg,

I'm envious you get to do this sort of tuning to your P220. I very mucgh like the OHV redblocks. I teethed on the metric B20 in a 1975 244 DL and the mighty B30.

I'd guess one would also discern tappet condition for wear and verify the pushrods remain straight and not at excessive wear at either end. I'm unsure where case hardening begins and ends as part of your cylinder head recondition and rebuild.

At any rate, I did some searches for this info:

- These camshafts fit B18 and B20 pushrod engines. Volvo has used different camshaft specifications, please check cam base diameter and cam height when ordering sports camshafts.
Depending on the engine version and application, extra modifications may be required.
- steel billets with [fuel] pump lobe between 2nd-3rd cam, and [oil pump] gear between 6th-7th cam

Hope that helps you.

Happy Sunday.

(Though I'd hoped for the B30 in a 164, someday.)
