Thanks guys.
I have had this car for a while but it never had a thermostat in it. It never had one when i got it and i must have forgot to put it in when i rebuilt the engine the first time? (dumbass)
So the only time it had one was just before the head gasket failed and i know cars run hotter when coolent is leaking into the combustion area so yeah. Now it's going again i expected it to run a little cooler but i guess not. have only put about 10km on it since fixing it as she aint regestered and it seems like it might have consumed some coolant.
The head should not be cracked as i had it pressure tested the same time i had it decked. I checked the block to true and biggest gap was less than 0.05mm and im using a MLS cosmetic headgasket and ARB headstuds.
It may have just bled some trapped air out of the system...
I guess i better get a hold of a pressure test kit from somewhere and pressure test the clt system. See if it fills the sump/head up with coolant.
compression test came up okay. A little low but nothing obviously wrong.
Thanks for the Heads up about running temp, It sounds like it's normal so it might be okay. If its a cracked head ill be a bit pissed since i had it tested and it came up okay. If its a cracked block them ill probably flog this car off along with the 2 spare parts cars. If it's neither i'll be stoked.
