My heads were welded in the push rod area to pick up more room I guess. I can see all eight rocker stud holes in my intake ports. I just sealed the studds as I installed them

I went through the wall of one of my ports (intake) when porting my heads. It was due to a casting shift right in the pushrod pinch area. I just took it to my machine shop and they hooked me up with the guy that did all their aluminum welding. Two days later it was fixed and I just smoothed out the welds and finished the rest of the porting.

From my perspective, and with resources at my disposal, I find it foolish to open the cross section area, in the push rod area 'blind'. IOW, I see a small but worthwhile investment in time with a height gage, to determine the exact the wall thickness, and more importantly reference lines to work with, to know precisely when the wall will break thru. This time investment required to do the layout work, pays dividends, if it means preventing time and money in weld repair.
