Hum, those were for the 2.8/3.1 so I am not certain they would work....

They have the
Gold Race Rockers which are more like mine.
I do remember now paying almost $300 for them,
so I was
wrong about getting them cheap!
ANd yes they will work with any head stage 1-3.
Though custom push rod lengths may be required.
I'm not certain about MMS's head specs as he keeps this hidden so people like me cant copy them for less
But when you goto build who ever does this will have to measure the geometry and lengths.
