It may be. The heads from the later engines with Ultramatics were higher compression and with the milling it may be even worse. With the extra squeeze of the larger piston displacement that could throw it over the edge with pinging or knocking you cannot totally eliminate. I'd also be a bit concerned with valve clearance so be sure to check that before bolting it down.

Ross posted the heads he recommends some time back. Perhaps he will repost them or someone will remember that thread or discussion and link it here.

Is the 53 block cracked on the outside or in some way totally unsalvageable? When I did a 54 back in the 80s one of the cylinders was cracked so I had it sleeved. I sold the car but it lives not far away and the car and engine is still going strong today.
