Im currently porting some 862 heads i got for cheap. Im going to get the TSP cam set which includes the cam, pushrods and springs with seals. My question is what valves seals do i get? I get two options either the 1 or 2 piece valve seals. The hat looking one or the normal seals. My current heads came with the hat style.

v2 112lsa
862 ported with ls1 intake valves milled to get 59-60cc
3200 stall
+supporting mods.

 

Get the hat style from rockauto, that's what I did

 

Hat style are stock seals. Dual aftermarket springs take the posi lock style seals.
