Anyone build a high RPM 273 using 2.02 size head?

Drop some magnum heads on it. 1.916/1.624 and keep some compression. A ~69cc 2.02 J or X head on a 2V 273 is gonna tank the 273's already low compression.

Came here to say this. Add a nice fully profiled hydraulic roller and I think you'll be set.
