I have several questions as I begin a 261 Rebuild.

Are there .070 pistons still available?
We are on .060 bore and it's not great looking and am not sure we can get away with a hone job.

What is max safe milling on head and block WITHOUT modification to pistons to clear valves?

I assume we use all our clutch and bell housing from the 235 in the car now? Can I use a larger clutch inside stock 1953 235 car bell housing?

Thanks
