4.120” is standard bore for the 428.

4.160” is +.040” for the 428 pistons so you’re poking that 421 .06625” over which seems excessive unless the...

The first run E-heads used five different head bolt lengths unlike the later versions so that set of bolts will tell you right there without measuring anything.
