I was hoping to get some input about my 1954 Packard. I'm in the process of putting the engine back together after being rebuilt. It's a 359 with a 288/327 head. I did not have the head "checked" but visually it looks fine.
JMHO, but I'd never consider a Packard I8 rebuilt unless the block and head mating surfaces had been milled.
Some have been able to get the two old pieces to seal up without it, but I'd not take the chance.
We put heads and blocks on the mill every day and it's a very rare piece which the first cut is even across the length and width, indicating it was flat as was.
Most have waves, dips or warps and it requires removing .005" to .015" to get them back flat.
