Title says it all, 2.7 litre six w/ crankfire ingition, Webbers & RS pistons (10.3/1). Running Splitfires now- came w/ the car. Suggestions? Thanks!

"Splitfires"?! Been a long time since I saw those sorry POSs. NGK plugs work well in 911 engines. At 10.3:1 you're probably gonna want a cold plug, something like a B8ES, but I could be wrong, because Webers tend to run fat. Best places to ask might be Richard Parr at PMO (http://www.pmocarb.com/), or maybe Clewitt Engineering (www.clewitt.com). The Cap'n
