i have been having a problem when the car is cold. once it is started and begins to come up to temp-the gauge continues past 180 and goes to around 210 before settling back to 180. it doesn't do it all the time and usually just when the car is completely cold. i have done the following to troubleshoot; replaced the t-stat [twice], ensured that i don't have air in the system [letting come up to temp-once antifeeze starts to circulate, then top off]. i have also run w/o the t-stat [temp seems to stabilize around 145-150, and don't experience the problem. i don't want to damage the head by seeing this temp spike each time i drive. does anyone run w/o a t-stat? if i do this, any problems? also, i run a 4 row rad, oil cooler and elec. fan, L28, p90 head, jcr supercharger setup. any help/feedback would be greatly appreciated!
thanks...
