Another very mild 440 build.....

I mocked them up on a 383 & realised I'd have to notch the bore. I think 440 source recommended no less than 4.320 standard 440 bore. The 413 is smaller so it will need notching.

Thank you. I put the TF240 head on a 4.25 bore and found that the 2.19" intake valve hit the cylinder wall at around 650" lift with no head gasket. However I don't recall testing the exhaust because they were only 1.76". The old 426 Max Wedge engines with a 4.25 bore and a 1.88" exhaust had the block notched.
