Who's rockers are these?

That was me, but it’s actually only 1.5 intake rockers for the non-Chapman MW stage 6 heads(they are like the rocker in my pic above).

My recollection(which could be totally wrong) is that the Chapman heads used rockers that were specific to those heads, and were made by T&D.

If you could find the 470 build Steve Dulcich did using those heads for one of the Engine Masters contests, there might be some pics of what he used.

Streetwise over on Moparts was also using those heads on a low deck build.

As for the particular rockers this thread is about........ I still try and avoid Chinese rockers if at all possible.
