What do you mean you thread the heat sink?
The nova heads are very good. Excellent quality and will lower engine temps too. But it depends how much life you have left in the engine. It might be a better investment to just put the money towards the OS.
cheers for the reply keith
i mean when i screwed in the plug it must of been at a angle and now it just screws and screws and wont go tight as its meant to go
there is plenty of life in the engine yet and im not bored of the speed. if i go os is the the TZ i shall be looking at ??
decisions decisions
so the nova heat sinks will be a good replacement until i have enough to buy a os.... will i need new gaskets. ive never had the heat sink off
