did not buy RHS heads

Hello:
I contacted the vendor that had the RHS heads and asked what parts were in the heads...Comp Cams parts were supposed to be in them...His reply was that they were not comp Cams parts...He gave no additional information as to what valves, springs and retainers were in them....
So, I went with the Summit Racing Vortec heads....They are made by Dart, as many know and I am really impressed with the quality of the heads....67cc chamber w/1.92 I/1.54E Now after drueling over them for about 5 min. I saw how nice the Intake ports look as well as the exhaust ports...I am really wondering if these are "sleeper" heads~! The ports have no real ridges in them like the old fuelie heads did where you had to take a dremel tool and smooth them out...Also the intake gaskets are so close, that I am not going to do anything to them, as to matching them. Both set of valves were undercut before the seat! I did not expect that, but they are..Overall, although the claim is 232 cfm on Intake and 139 on Exhaust. I have a feeling these might flow more~!
I think I got a woody~!

PMW vortec rocker arms

I also ordered and got today PMW vortec rockerarms with the roller tip....I did some investigating on the internet and saw good reviews on them, so I took a chance on them and they look pretty good. I pulled them out of the package and really looked hard at them...The quality is there and they appear to be very heavy duty...1.52 ratio is stamped on them, so I am curious how close they are to that spec....

I have been looking at suburbans in the same yr range (up to 86) an it looks quite easy from what I saw of the frame mounts on the front end. I am curious if these parts could be harvested from a suburban and bolted and welded into place. I already know that I need to get the undercarrige out of mine and the burb's into mine. shock mounts and spring mounts, tranny mounts, ect....
Thought I would do an update with all the recent research I have done...I was going to use the Lunati 60101Lk cam. But after learning about recent oil anti-wear additives, I have decided to go with a Hyd. Retro Roller Cam...

I have narrowed it down to these 2 cams:
Crower 0409 retro roller
http://www.summitracing.com/parts/CRO-00409/

And Edelbrock's 2208 retro roller:
http://www.summitracing.com/parts/EDL-2208/

For a comparison, here is the lunati flat tappet cam that is being replaced with one of the above cams:
http://www.summitracing.com/parts/LUN-60101LK/

If you were to choose between the Crower, or the Edelbrock, which one would you go with considering I am using Summit/Dart vortec heads and a Pro Comp airgap intake with 3310S Holley 750cfm carb....

http://www.summitracing.com/parts/SUM-151124/

I am not interested in different cams from other manufacturers because I plan on staying with the valve springs in these heads...Which cam is the better, or as I see it, there is not any difference, or not enuf to notice in the seat of my pants...So far, Edelbrock is the cheaper price doing a search on the internet...About $295 shipped....
