Not alway's. I have seen it done on both chevy and ford + plus 1 500" caddy early mud bog engine.
Look at chevy 348-409. The first time I ran across it being done 35yrs ago, was done like
a 409 on there small block. Current you are right on but years ago you could see both way's.
It's cool we are looking at cutting edge history here, everything was tried then. Never know
what you might find on a vintage engine at this level of trick.
Thank You TT5.9 for adding that onfo as any angle milling here is on the high end side of
building. This helps everyone.
Thank You again,
Rick
