Saw a post on Facebook tonight and these parts are now available. Very excited to order some up I have a predator non hemi head I’m going to build with these new 5mm stem stainless steel valves. Not sure what block it’s going on yet probably a 196 clone but I have really been wanting to build a Tillotson block. We will see!
