I know you will put them to the test. and give a very honest review of the OTB heads.
I'm not in the market for a small block head, so I'm in no hurry.
They certainly don't have the spring pressure of my cast-iron heads at 360 but at 320 I'm sure they're going to hold the 6K that I max the car out at these days as it doesn't really go any faster past that...
Plus the cams no longer at 603 lift it's more 525...
