Squares Or Recs

A 1990 Chevy C1500 454SS has oval or rectangle port heads?

[Draenor]

Dont take it as gospel, but It should have rectangular.

[Nytemare]

Pretty sure 87 and up 454 had rectangle ports. But again, not 100% sure.

Thanks a ton... Now for another question. Does any one know what type of cam it comes from the factory with? Hydraulic Standard, Hyd. Roller, Hyd. Flat Tappett, or what... I am trying to convert to carb and would like to do a few other mods at the same time. Any help is appreciated!!!
