Well we are doing the pi headswap and we found out that all 8 of the valves are burnt!They were all red cherry red!The night that i got my car it freakin hauled ass,like it had never been hossed on..Then we noticed after all of the hossin we did that night it was runnin really hot.It was like almost on the A.So the next day we replaced the thermostat and did a radiator flush and it still ran hot.After that we decided put a switch on the fan.It never got hot again until we gave it hell or ran the air conditioner.Hopefully after all of this we will see a drastic difference with the comp 270's.What do you guys think?
