Were do most guys tap for getting better water flow to the heads? I Was going to tap the back of the intake and run it to the water neck....is this a help or a waste of time? What about the plugs on the heads can i run lines from there to the water neck or what....i am just looking to get better water flow to the heads....any info would be great!!

Here is another on the same line....when you add the block under the water neck for the water lines do you put the t stat in the normal spot on the intake or the top of the block?

Use a water pump with provisions to run water from the pump to the center of each head . You will drill for a -8 fitting just above the deck surface of each head , and just under the header flange . This will put cold water between the two center exhaust valves . Yes you can take water from the back of the intake and plumb it to the water neck with no problems . Most water neck block's are not designed for a thermostat , and you should not be running one anyway .

read an article once reviewing a hendrick winston cup engine. it explained that the coolant lines running from the back of the block/manifold aren't actually placed there for the primary purpose of coolant flow but rather to avoid air locks at the back of the block, but they are definitely worth while.
next time we strip our engine i'll be plumbing the center of the heads like steve suggests.

Well i plumbed water from the back of the intake to the water neck riser...3/8 line. No the question is i have a t stat in the intake and with the lines hooked up the water is bypassing the t stat.....am i missing somthing here.....will it heat up this way?

I have allways run a 160 t stat in my mod....should i just use a restrictor and if so what size should i put in? I run a small rad and my cooling system only holds about 2 1/2 gallons of water. I have the kse mandrel gear on the bottom and the gilmer belt on the water pump. My motor will get up to temp pretty quick unlike most that can sit on 140 deg till they race(they have the big rad). Should i go small on the restrictor or big....can someone give me a starting point i have a race fri and the air temp has been in the 100 deg range. Thanks, Craig Moore

I would run the rest. to slow the water down abit. I've never ran a stat but that is me.

Hey Dustejr73 have you ever run them in the intake? This winter we will be also plumbing the heads.... i needed it back together for fri or we would have done it now...I am still up in the air on the restrictor deal thow im thinking about the 3/4 one. What water pump will i need for plumbing the water to it? I have the KSE pump that blocks the pass side and the driver side has no hole or boss that i could tap. I have 1 more for ya..... why couldnt i just drill and tap the intake in the water runner on each side of the water neck? Thanks for all the replys!!

For anyone that was reading this post and waiting for a good starting point....i went with a 3/4 restictor and the motor ran 180 degrees in the heat ....till i burnt up 2 pistons .....while packing for about 20 min it was about 185 and took a bit to get up there....This is with only 2 1/2 gallons in my cooling system.
