sounds like a fun day was had by all.but seriously.i wa spreparing the sunny for a supersprint at wakefield park about 2 weeks ago,after replacing the dud radiator,& when i undid the sump plug,about a litre of coolant preceded the oil out into the bucket.lots of rude words,one blown headgasket.it was blown on all 4 cylinders,was probably weak already & the overheating was the last straw.so,off with the head,new gasket,(no we didn't skim it,lazy us),new gasket on,all of a sudden it's sounding really strong again.on the day we suffered from fuel surge in the tank,manifold studs loosening off due to a lack of lockite,but overwise the car went like a shot dog.the worst part was i wasn't driving,i was doing the timing in the tower for the event,i let a friend who'ed done a lot of work on the car use it,along with my usual co-entrant.oh well,oran park grand prix on the 25th.
