What do you guys think of the speedmaster bare aluminum heads
That is my question also.
Pushrod oiling is typically associated with the magnum style cylinder head.
It can be used on shaft mounted rocker system on the LA (273, 318, 330, 360, ++)
Usually I do not see pushrod oiling outside of the stud mounted magnum based cylinder head.
Edelbrock makes an aluminum magnum head, mopar, China and RHS INDY made a magnum based iron cylinder head.
By China could include ProMaxx, etc
