SM Head Modifications on a budget

I’m enjoying your journey.

It does seem like you’re going thru a similar situation I described in post 181, although you’ve done even more exploratory work without unlocking any secrets/magic yet.

In the last port mold pic, the SSR looks a bit worse than I’d imagined.

I kinda lose interest when the clay makes its first appearance. A 280-330 cfm Speedmaster needs less material, not more.
