I do know that it is ez to have coolant leak into the oil if over torqued





That was my reason for asking. If you look at the vertical bolt design there is potential to put huge lifting forces on the heads (compromising head seal). You are essentialy driving a wedge between both heads. As the aluminum intake heats up those forces increase. I just did a SB with magnum heads and had an incorrect torque spec (35 ftlb), I think this could be the reason why there is some coolant weeping on one head. An intake re-install with head re-torque will be needed.

Also a quick note for anyone looking at buying a magnum intake, the chinese air gap intake used on this motor was not machined correctly on the intake surfaces (wrong angle) or the valley end seal surfaces (interfered with block). This was the first time I actually used one and not sure I will again.
