Cylinder head temp?

Hi,
Just a quick question,what cylinder "Head" temps should you see at stage?
The engine in question is 315" SBC with a "D screw" and a pro mag 20.
Data logger has a provision left so where gonna try it. Already have 8 egt's and was just curious as to what numbers SHOULD be seen!
This is a cast 13* head deal not billet if that matters
Thanks Jason....

 

where will you mount the temperature sending unit. I also have a non-water block and motor and wanted to run a cylinder temp gauge on the data logger, but did not know what gauge or where to install it. Mine is on a conventional headed BBC

 

Ours is BBC, no water in a water jacketed cast alum head. We drilled/tapped a hole parallel to the deck surfaces, centered front to back and just close to the deck surface (down by the bottom row of studs). Than use a ring terminal looking like temp sender.

I'm not sure there is a magical temperature number, my thoughts are its more of a consistency thing. Be repeatable and then start experimenting with different temps.

Hope this helps!

 

I ran a blown sbc with cast heads for a long time................i would strongly suggest you run water in the heads.i had a filled block ran water to the back to the front of the head into a small radiator.

 

Water in the heads??

This is a solid billet CN block with solid 13* heads! Not much chance of water leaking on this set up! Besides,waters just another thing to leak

 

are these the racer pro heads?
aussie made?

 

Racer pro 13's!!

Yep! sure are....
Jason.
