Head bolt holes

[captainron]

Anyone know which bolt holes on a Stage II 4.1 actually get into the water jacket of the block? Just trying to avoid any leaks from head studs when putting the GN1s on...... Thanks

Only the 8 bolt holes in the same place as the stock heads go into the water jacket. The "extra" holes are blind.
