I found a set of Vortec heads on Craigslist.org local to me but want to get some opinions on these first... Here is the link to the ad first: http://charlotte.craigslist.org/pts/1579716730.html
Here is the email the guy sent me when I asked him about them:
These are 1996 heads casting #906 wich were the best flowing out of all the Vortec years coming stock cast 170 cc intake runners. I can always port them for you a little more if needed.The ones in Summit can be any year but come with pressed in studs no guide plates and very weak stock springs.I bought these heads out of Craigslist 6 -7 months ago for $300.00 and they were used just pulled off a motor oily and gasket still stuck on them.I did not trust them so I took them to Carolina Crank and had them checked out. They were good no cracks,pressure checked, etc. But valves were beat and in need of valve job.I built them up for my 383 i was building. Brand NEW stanless steel valves for nitrous, NEW 3 angle valve job,had the heads drilled and tapped for screw in studs, NEW 3/8 screw in studs and pushrod guide plates installed,face head machined flat. Upgraded the valve springs to a heavier Comp Cams spring but stayed in O.E.M. valve o.d. spring pocket as to not spend more money machining head they are 1.255 o.d. but can handle a .550 lift on a flatt tapet cam(stock hyd) non -roller they had a 125lb seat psi. and a 260 open psi. all brand new with new retainers and 7degree locks and teflon valve seals. Cost me another 350 to get them back, they are still in the bag from machine shop, never used or bolted on. I later on bit the bullet and bought Dart aluminum heads new for $1500 so I need the money back that I spent on these Vortec iron heads. These are bolt on 35-40 HP over any other GM factory casting and allyou need is a set of roller rockers from summit the cheapest set is 150 procomp.
Anyways, that is the email I got from the guy on what the heads have done to them. I was thinking about offering him $450 but not sure, I do not know much about these kinds of things so looking for opinions.
I have a basic 455 lift hyd cam, I believe its a Comp or Crane. It's a low engine torque milage cam that I plan to use on my 355 build for this 80 El Camino of mine. Would this cam also work on these heads if I went with them? I am guessing so since he said they will handle .550 lift on a flat tappet but I want to make sure he isn't feeding me some BS.
Thanks for any information, opinions or suggestions! Right now I have some '72 3250 stock heads but would rather run Vortec. I just do not have $700 for new Vortec's from Summit right now...
