It’ll probably add about 30-40* of seat duration at the valve.
So you mean the valve will stay closed longer, effectively reducing the duration at .050 to the 206-216 degree area? It's a tight lash cam spec'd at .020 valve clearance.
No..... I mean the exact opposite of that.
Running hyd lifters on a solid cam is the same as running it with zero lash......... because thats how much lash it will have....... zero.
