I've been having a bit of a discussion back and forth with Kaase's shop about the valve springs. The net cam lift is around 0.780 (gross lift of 0.800 with 0.020 lash) but the valve springs they supplied with the heads are rated at 0.730 lift. (Manley 221443)
The guy at Kaase's shop tells me that they run those springs with that cam but I have my doubts. I hate to doubt anything that Kaase says but the math doesn't seem to quite work out right. We're going to mock up the head again and double check everything. The Manley springs are expensive so I hate to have them go to waste. A high quality spring + retainer + locks combo goes for about $1000 these days. Prices have basically doubled in just a few years on some of these parts.
