i was told these were straight up horrible from another member... and to throw them away! lol454C10 said:882's aren't bad for a mild build. If you plan to build a mild engine on a budget then use them.
A little DIY bowl smoothing goes a long way on those heads.
If you are building a truck engine with an auto trans and 3.08 gear then use the q-jet and stock cast iron intake with a set of full length header and a short duration cam.
Trust me- there are far worse heads from a street performance standpoint. The TBI heads used later on, like the 14102187, -191 and -193's are all pretty bad.andy_s273 said:i was told these were straight up horrible from another member... and to throw them away! lol

Then there's all those 1.72 x 1.50 350 heads (some c/n's 261, 624) that were on trucks and even Blazers in the 70's- some have 3/8" exhaust valve stems to boot!
So yeah, there are worse out there.
I wouldn't put one red cent into the 882's, though. Spend some on fitting your Vortec's w/better springs, etc. to allow for more lift.
BTW, your 882's should be checked to be sure they don't have the 3/8" exhaust valve stem- just to be safe. I've not seen the 1.72" intake valves in 882's, but I can't rule it out, either.
I don't think anyone took you to mean they were. I didn't, anyway.454C10 said:Never said the 882's were better than vortecs.
While shortening the valve guide is one way to do it, there are ways to get enough clearance between the seal and retainer w/o machining anything, or by "ghetto grinding" the stock retainer.L31 vortec heads flow better, no doubt, but also cost more to run as they require vortec intake, vortec rockers, vortec valve covers, and require machining to run more than 0.450" lift.
This is the first time I've heard this. About the fulie and 441's that is. I've never been a fan of the S/R's.882's flow very similar to world S/R torquer heads and better than the old fuelie heads and 441's.
