Edelbrock heads possible rocker shaft thread issue.

[Keith Stevens]

I tried to locate the lockers to no avail. I ordered the Time-sert 3/8-16 kit. I'm running POP shafts,roller rockers, stands and his ARP stud kit. I'm at about 130 on the seat and 345 open@.580.
It's a flat tappet hydraulic cam. 242@ .50 and .578 lift. Hopefully all is well.
On another note time-sett offers a tool to keep the drill and tap aligned with the surface. I purchased it as well. I was concerned with using Heli-coils.

    What about drilling out the rocker stand that has the oil galley while still bolted on the block? Just flush it out by priming the oil pump with a drill? I'm pretty sure I pulled some threads redoing my intake last time. I have a new full set of gaskets if it's just better to pull the head(s). While I'm at it, would it be recommended to go ahead and EZ-Lock all 4 bosses on both heads before there's a failure? Seems like it'd be wise to just get it done and over with.
