Valve guide & spring seats on Stock heads.

[Myron Piatek]

I did found a beehive spring I'd like to use. A standard spring with or without a damper wouldn't change anything. I'm just trying to get some sort of consistency as to what to expect in tech with the machined-off step - considering the rule change. Or if it's an "it depends on the tech guy". Hate to discard otherwise good heads if it's actually been allowed before.
I wish I remembered the person and configuration I saw with Chevy small block springs on a Mopar small block Stocker.

I've seen other similar rules discussed here allowing something new, but being unable to use it without doing posted illegal mods. The Edelbrock small block Mopar heads come to mind.
