I see a few people on this board are using Head Quarters heads and other parts on their motors. As you can see from my signature I'll be running their heads and cams on my 95" build this winter. I'm just looking for some feedback, good or bad, from other people using HQ stuff. Thanks!!:chopper:

I had Head Quarters parts on my Lowrider. They did not do the heads correct and after waiting over 2 months to get them back the first time I was not sending them back to them. Instead, I just decked the heads myself and installed them. Afterwards, the bike ran great. More of less running the same set up as you are looking at. I had a Mikuni carb on the bike. Take a look at the dyno run attached to my signature. This thing pulled very hard and would embarrass those little rice burners from time to time. Tough to keep the front tire down when you crack the throttle hard. Passing cars and on-ramps were a lot of fun.

What do you mean they didn't do the headsright? Could you elaborate? Thanks - Kurt:coffee:

They did not mill the heads properly. I asked for a 9.75:1 and it was actually about 8.75:1. I think they forgot to mill them after they ported/polished them. After I milled them down it ran great. They do a goofy lip on the bottom of the heads that the gasket goes around. I think they just forgot to finish them

The goofy lip is called spin dropping

Now that the Cometic .030 head gasket is so popular, people forget that they only used to have thicker head gaskets. They do the spin drop milling on the head so that the proper quench can be achieved with a standard head gasket. It is not needed today as much as before due to thinner gaskets being commonly available. The lip sits inside of the head gasket dropping the head closer to the piston.
