New 408 build finally started

View attachment 1715499159 View attachment 1715499160 Ya I’m at 1.300. Would I have had to go that far? No but it sure let me do nice things to the curved wall. Checking with some shims and the lockring I moved the rocker over .283. Minus the .050 shim I usually have in there for adjusting app .230 needed. That’s where I started and now I will back it down to see how tight I can go before rubbing. There is still room to grind more out especially on the bottom because it’s out of the port window. I gotta see if I can get my sonic checker to repeat so I can trust it. It’s not like I couldn’t repair a hole, I just don’t want to have to. I want to check actual valve lift now to see where I’m at.

So .230 plus what you have ready in the rocker (was it .350?????) makes you .580 and that’s less than W2 offset. So you could either have 8 custom offset rockers done up, or you could just order 8 W2 offset rockers.

Either way, it’s not cheap.
