Edelbrock Heads Sound Like They're Terrible

Nothing..I repeat NOTHING should be bolted on right out of the box...
I just fast forwarded through the video,but those VSI washers are hard and pose no problem for joe average with his 230@50 type of cam.Sure a cup would be better but the person who would be thinking about using these heads OTB would never pay the extra $$$ to machine for cups.
The other thing is always hone the guides,every Ehead I've had in my hands have had a couple of tight guides...
In the 35 plus years I've been doing this I've NEVER seen a part that I would use straight OTB...
