I thought that with modern multi layer gaskets (cometic etc) and decent head bolts to really clamp up, wire ringing was a little superfluous and
potentially not as reliable as a decent gasket?
How much boost are you running on the beast now to hit 12 second quaters?

ran the 12 sec on around 15 psi, engine ran 28psi on the old bosch management, but its not been mapped above 18psi on the omex ecu yet. Owner tried
upping the boost a touch on sunday crudely by just adjusting the wastegate (long story, but it has a boost controller though! ) and lost control of
it, it spiked 30psi and blew the head gasket........
it is a multilayer steel gasket already!
The gasket isn't the end of the world, as its on head studs, so just a new one will get it going (we use a zafira VXR laminated steelcgasket,
£23 new genuine oem part ) but we want to bulletproof it, and as its always coming apart for some development or other (read buggering about with it!
) then cometic gaskets are too pricey.
Its rather quick though, to say the very least. The 12 sec really doesn't do it justice. The terminal was 127mph, which is slightly more
indicative (the second half track is where it actually can put the power down)
I took it out the other day on the road running 15psi, and 5th gear is the only gear where it grips without lighting the tyres up (and they are soft
compound toyo 888's) and given any reasonable straight stretch of "private road" it hits the limiter in 5th, around 165mph 
All in all not too bad for an engine that has so far cost less than £2000 including all ancilliaries and ecu etc.......... (its still on a stock
bottom end!! )
