its really late but i have questions hopefully i can finally get answers. on the thermostat issue would it be practical to perform this on a street vehicle that sees no track use? i drive very spiritually and thats where my concern is.if it is practical could i just use the same thermosat in the head and not have to modify it like they did?they said they modified it to keep pressure up but i wont ever be on the race track. the part is only a few dollars and i have replaced them b4 on my previous engine its really easy. i know i wont get any answers to this but heres hoping
If your referring to them useing same thermostat in both to keep the head and block temps the same your just wasting time unless your all out hard core like them. You won't have any issues the way it is now.
