Any one have a part number for retainers to get a 2” set up height on my 440-1’s? The ones on the heads now set up at 1.950 with a .015 shim. I have no idea what the part number is on them except that they came on the heads. Heads have had zero additional machining. 10degree titanium. 1.550 spring.
