Milled 289 heads, just until clean up Chambers came out 56CC, puts my compression at 10.07:1, was going to do a small dish in the piston if needed but I'm just going to run it like that.

Ran 289 heads in a similar setup back in the 90's on pump 93. Sometimes it would run on a tad after turning it off, but no audible detonation. A buddy with the same heads on a 306 had to use octane booster and 93 with flat tops. I believe his cam was only 224/236... but a little more compression with the 3" stroke, compared to your 2-7/8".

After looking at the advertised duration, I may end up putting a dish in. The last 289 I did used the 282S cam, older style longer seat timing. The nostalgia plus cam is 262/269 and 112LSA, I wish I could find a 282S.

Especially being someone else's engine and using the smaller cam... probably a wise decision. 282S is a great cam for a 6500 rpm 289! Surprised it's unavailable.

I ended up finding one in Iowa

With the bigger cam and a 289 you can likely do fine with the flat tops.

On Jim's 427 FE carbs, he cut the primary shafts for Teflon strips, secondary come that way already. and Jim removed the idle feed restrictor, moving them down to the lower position below fuel level.

Working on the 427 block and crank for the tunnel port heads.

Fixed a leak on the 427 TP block by the water drain, silicone bronze with the tig.
427 crank, had a few water spot but I think it will run ok, and it looks a lot better than when it showed up.
