We assume those are mid 80's 305 heads. If so, your valve lash is off.
Rocker arms are not "torqued" on these.
The book wiil call for 1 full turn past zero lash. A lot of guys will have a preference of 1/2 turn past zero to 3/4 turn past zero lash.
The engine will run at zero lash, but you won't be happy.
I'm concerned about the rockers being "torqued".
Firing order will be clockwise on a SBC.
