well the ups man brought the backordered heads today.. I took pics and will upload them to my site when I have time (full time grad student)..

Initial inspection.. not bad! definitely a cut above stock.. they have some initial cnc porting to smooth the intake and exhaust runners.. maybe 1/4 " of it on the exhaust side and 3/4 to 1" of it on the intake side.. The casting looks good essentially like a ported head with a cast finish.. the area around the valve guides is smoothed and shaped and the short side radius has no ridges on it.. valves look like manleys with an undercut stem.. springs are singles with a damper.. though claimed up to .600 lift the booklet says they are only reliable to 6500 rpm as a recommended max safe rpm..

so I thought I may have some work done to these but they don't seem to need it.. at least not for my application.. the only problem I see is the small runner volume (170cc).. other than that not too shabby..

 

Backordered, eh? Didn't know there'd be so much interest.. kind of surprising. Keep us posted!

 

Anyone have any flow numbers for those heads?

Was going to get them flowed.. but as a student I am now too poor to do it.. the best I will be able to get is pics, and track/dyno numbers eventually.. I will be using a 224/230 cam with these and a program from madz28.com...

the ports look good, after reading the threads before I thought I would end up with two boxed of scrap aluminum, but they are quality peices.. with the concerns mentioned about runner volume above.. they are also heli-coiled for the headers which I thought was a nice touch..

Deck thickness according to the manual is 5/8ths.. spring daimeter 1.450, installed height 1.8, 120 lbs seated, 340 lbs @ .600,

regardless I know this doesn't get down to how they perform..just my out of the box impression.. they should go in this weekend if I get enough time..

 

and???....its been a month...how are they?

 

Well that was before Isabelle came and rocked my little house.. to top that off my 4l60e broke a planetary center gear.. soooo

I had to trade them to go with a six speed swap for the 82, but in a funny coincidence my roomie bought the heads off the guy I traded for the tranny.. so now their home will be a fresh cammed lt1 in a nice caprice...

I will still be able to tell you how they work for him.. Unfortunately not for me!

 

I actually think those heads will be better off in a Caprice than an F-body. Why? The small runner volumes will promote good intake velocity, leading to better low and midrange torque numbers...exactly what a Caprice/Impala needs.

 

Is your buddy in a hurry to use them? If not, I'd flow them if he'd pay to ship one head.

Color me curious

 

whats the cost on those heads? they came FROM edlebrock with springs and valves n all that stuff? ready to toss on?

 

I'm curious too.. he is putting them on late this week so no go on that..

as for price.. they are like 530 per head complete.. with all the stuff I mentioned in one of my above posts.. ready to put on.. they are part number edl-61909 from summit..

 

thats not bad at all! so 1100 bucks.. hmm.. and they are better then stock.. Now the question is how do they perform
