No not poor quality, just common sense says to look a part over before you bolt on.
COMMON SENSE ? .... so if you buy a complete motor or transmission ... you should DISassemble that and check-all the internals?

I can understand changing the locks (and springs for high lift cams), but why change the retainers if you're not racing?
Something wrong w/them?
Seems like a waste. I think for added insurance, the heads should just come with 10* Comp locks.
For sure! I couldn't believe when the guy at 440 Source told me I had to change them because my cam was over .510 lift. Are a lot of guys buying aluminum heads and running small cams? Should just come with them standard IMO. So far that is my only complaint. I still don't have the motor assembled so I can't tell you how well they work!

Double check the fitment of the head gaskets to make sure they do not breach the chamber.

As consumers we should at least expect that a set of heads that costs from $1000 to $2000 and are promoted as bolt ons should at minimum have a proper valve job including spring heights and stem heights etc.
Personally I think everyone takes the "bolt-on" or "ready to run" statement too literally.
Buying car parts is no different than buying a door at Home Hardware - it may need some material shaved off the edge before it closes or need the hinges moved a tad to fit.
Or how about buying a "ready to serve" TV dinner - sure its ready to serve ... AFTER you heat it up.
And then there's the fact that car guys are a picky bunch. I don't doubt that those heads are WAY better out of the box than any head that came on your original car BUT ... someone tore a set down and they weren't absolutely perfect so now everyone is expecting Super Stock quality parts when that was never the manufacturers intention to provide.
Let's face it guys, $1000 for a pair of aluminum heads is pretty damn cheap. And if you bolted them on with stock hardware (what they're made for) they'd likely work just fine and give you years of trouble-free service.

As my machinist said they werent bad for a grand.They arent a $3000 set of heads.If my motor wasnt so radical and 4 speed I could have run them pretty much out of the box.But with a .588 solid cam I swapped stuff.Im still happy with them for the price.Even if they were hi buck heads I would have them checked anyway.Rocky

Not too start an argument here. But I have to say I disagree. A bolt on part should be just that. I manage a Lumberyard / hardware store. When we sell a door it is ready to install. You don't need to adjust the hinges or trim the edge! (atleast not on a prehung door) If I was selling just a door slab that a person was going to retrofit into an old door frame...then that would be a different story. But I wouldn't advertise that as a "bolt on" type part. (like the heads are) If they are selling them as a "bolt on" then they should be ready to install. I can't even imagine selling someone a new steel entry door and then they had to move the hinges and "trim the edge". Just my

The 510" lift max of the stock springs is probably due to the fact that the heads are a stock replacement type head- and compared to stock cams a 510 lift cam (509) is much much bigger/aggressive than stock. ???

That makes sense. I guess I don't consider them a stock replacement head.

Are a lot of guys really putting these heads on a totally stock motor?

I would suggest that THIS would be a major mistake .. it could slow the car down .. big-time.
