With over .515" lift with stock valve stem length your retainers are going to hit the valve guides.
Plus you will never get an installed valve spring height of 1.7" with stock valve length.

Aaannndddd... That's why I'm using custom titanium (int) and sodium-filled inconel (exh) valves with a 1.8 inch installed height.

I know I'm pretty new on the boards, and I'm certain you just want to help and in no way are trying to be the a@@h01# you sound like, but that doesn't mean I am new to building things.

I will cover the details in my build thread soon.

I don't find the 2018 update, but the 2006 one is one of my favorites for oddball research.
Feel free to delete if covered elsewhere. ... manual.pdf

And of course the piston specs.
It gets 10MPG, but goes up to 14 if I lie.
