Re: 1948 288 Engine Head Refurbish

Hi Folks,
Many thanks for all the great info. Couple of updates:
1. The head came back from the shop. It's not too bad with the worst warp at 0.007". It does have some gasket etching as well. See picture. The shop recommends taking off about 0.010" to flatten everything out. Before they do this, I plan to do the modeling clay trick (torque the head down on the old gasket with some modeling clay over the valves, turn the engine over x4, remove head & measure free clearance above the valves). Once valve to head clearances are known I'll talk to the shop about going forward (or not) with milling.
2. Crack penetrating dye kit is on order and I'll test the block once it arrives. Hopefully no issues.
3. After reviewing some of the posts and speaking with the head shop, I decided to go the paint route for the engine head. Have some high temp engine primer and engine gray on order.
4. At this point I plan to go with the existing studs. With the exception of the one low one they don't seem to be too bad and the threads cleaned up nicely. My worry is that the replacement process (risk of breaking a stud) may be worse than just going with what's there.
Again, thanks for all of the help, suggestions and advice.
Best Regards,
Tom
