Bit of progress, managed to score some commodore cup yellaterra pre pollution heads, adjustable 1.65 Yella Terra shaft mount rockers, alloy finned rocker covers and a steel romac balancer for an awesome price. Got the whole lot for about half the price new rockers.
When I get my full licence I'll fit the tri-y's I have at home and fit the rockers. If I decide to use a bigger cam I'll fit the yellaterra heads too as they have double valve springs which would allow me to run considerably higher lift (and no valve bounce).
These parts on a commodore cup spec 253 with regulation cam and intake etc made 170rwkw in a VH. I purchased the performer intake from the same guy, and was actually on the same engine. With some compression, cam and a decent exhaust I'm sure it won't be too difficult to at least match that figure with the old 308 (although it's an auto).
When I start full time work (I'm still a student), I'll look into converting it back to petrol as it will be a little easier to make good power. Since I'd be lucky to drive it once a week, the price of petrol won't be much of a problem.
Apologies for the bad photos, I really need a new phone and it was dark when I took the pics
