Stupid BBC Dart Head Question

[MCSS86TA82]

My 86 Monte needed to go on a weight reduction plan so I thought I'd go get a set of aluminum heads. After all you can only do so much with the old cast 049 heads which weigh about as much as the car. So I bought a set of Dart Pro 1's 310cc unassembled. While they are still sitting on my dining room table I noticed that the rocker stud holes go right into the intake runners. This was kind of a shock to me because all the heads I've seen (cast gm's) never had the bottom of the rocker studs sitting inside the runners. Doesn't this cause a problem? I thought I would just trim the stud but I would still be left with cleaning up where the tap runs down into the runner. I was wondering how you guys deal with this.

Got it. Shorter stud length (ouch) on the intake rockers. looks like I just have to live with the intake runner wall that isn't smooth where the stud tap came through. I was thinking (there I go again) there was some magic epoxy that could be used to smooth that up.

You can use epoxy to fill the gap left by the shorter studs then after it dries you can smooth it down some with fine grit sand paper, the air/fuel mixture will never know the difference.

I wish I had a pic of mine, they were smoothed before, it pulled one heli-coil out so I pulled the heads off and had inserts put into them right in the port ... the difference on the track and dyno ... ZERO ...

Manley Magic Seal Epoxy #40187 is for intake manifolds and intake runners. Goes for $28. I have a kit in stock that I can send you.

Make sure there are no sharp edges, but I wouldn't worry too much. Look at how the stud sit in the bottom of my port...
