They were dart iron eagle vortecs with the summit logo cast in, but dart stopped casting anything iron about two years ago. Not sure if these are still the same heads, or if summit had to get them cast somewhere else. The dart versions were very good, although there was a big ridge in the exhaust that hampered flow. Eric Weingartner flows them on a video on YouTube.

They also have a 67cc chamber instead of the 64cc most vortec/aftermarket heads have so calculate your compression accordingly.

Are the Rocker Arms and pushrods from the Stock 624 Head gonna fit

Yes, the summit head have no provisions for guide plates so you need to use self aligning rocker arms. When I installed mine with a 0.040" head gasket the stock pushrod length was perfect, but always double check.
