rocker arm stud spacing
alright since apparently no one knew this in the other sections I figured some of you engineers might.

I'm looking for the center to center spacing between the rocker arm studs on an LT1 head. I think the spacing between the valve centerline is the same, but I'm not sure. hopefully someone with a little bit of technical knowledge of the LT1 can help me out.

in the pic below say the circles are the studs. I distances X and Y.

Same as the GM Bowtie Heads. The spec on the distance between the centerlines of the valves on those is 1.91". Those are the heads who's guideplates we use now on LT1 stuff all the time. I might be able to go accurately measure them in the shop as well, but I'm 99% certian that this is the spec for them.

Yeah, I measured 1.91 between the valves, but only 1.8 between the rocker studs. Do I have the wrong heads? haha.

No that's very normal, the rocker placement and the valve placement are different.

Bret, you have got to be the greatest resource this board has. If you ever find yourself in south Louisiana, let me know and I'll buy you a beer!

x=1.8"
y=2.8"

Re: rocker arm stud spacing ???
Ok so I've been wondering about this too.

So I could conclude that a rocker stud girdle for the "bow tie" head will properly line up with my factory LT1 head's rocker studs?

I ask because there are no rocker stud girdles available for the LT1.
