A ton more adjustability.
The flow characteristics are reverse.
You can lock them down.
Rebuildable.
Are full port when wide open.
You can get them anywhere.

Hey Glenn, I bought my Shockwave from Shockwave, and it came with a ball valve. Since it already had it, should I just leave it or should I take the time and change it to a ball valve?

Manifolds with risers and hoses. It seems to work fine, but it does run very cool, cooler than I would like. The owner of Shockwave told me to leave it wide open, that's what he tells all of his jet drive customers and he says he has not had any complaints. It just runs very cool and its not as easy to adjust, if I close it about 25% it runs really warm at idle, but really good while cruising (around 160). So with that being said, ive just left it wide open.

This is just me talking,  grain of salt if you will.

Replace the ball valve with a gate valve and adjust it so it idles at about 150 or so. It will cool off a little at anything above an idle, but might be better.

JMHO

Does it have a thermostat kit? Hope not.

So where is a good place to buy a gate valve?  I'm going to be running steel braided lines on my setup. Should I buy a certain type of valve?

I really like the Red and White brand,  but Nibco makes a great valve also.

Virtually any reputable supply house has what you need.

Get a 3/4" one,  not 1/2".

Roles way boats in upland says I'm ok with my ball valve and wide open. I'm running Mercruiser aluminum exhaust manifolds. I don't claim that I'm right. Just saying. Mine runs cool.
I once tried to NOT have a good time. It just didn't work out!

Mine runs cool too, just too cool in my opinion. So ill probably switch it out for a gate, or play with the ball valve a little more to see if I can get it to run where I want. its just seems harder to fine tune the ball valve just right.

You don't want it to run over about 150F at any time.

With the ball valve wide open, when I let it idle AFTER a good ten minute run, it will sometimes go up to 125 or so, but when im cruising, it is always down around 100.......... my gauge doesn't read lower than 100 so it could be even lower. It makes me a little uncomfortable but was afraid to mess with it, like you said, don't like to fix things that aren't broken. Im the second owner and its always been fine........ just goes against what ive always liked to run my temp at.

Me personally,  I would swap the ball for a gate and get it to idle about 150F.

This is of course if the water coming from the pump goes through the exhaust logs first, then the engine.

So what would you like to see as a temp, when running headers.  Based on this I am guessing it is different?

I have always considered the temperature differential more than a temp.

If the river/lake water is say 70F, you will probably want to be seeing a wot temp of about 120F. This wis equate to about  a 50F split between incoming and leaving water.  Any more and I feel you're asking for trouble.

Popular belief is under 60F and I tend to agree.

Thanks GT

Sounds like I will be needing to add a gate valve to my system.  I never get over 100.  Water is between 70-75, so I should be idling at about 125. 
This will be helpful.
Thanks
