Thanks for braking the silence Kev !
the mod was not cheap I must admit.
The cams were somewhere around 600 euro.
The gasket kit was around 150 euro.
New heads cost me about 150 euro.
The machining of the heads, the bored inlets and outlets on the heads, pressure checking and valve sittings cost me around 450 euro.
The rest, which were new hoses, clips, oils, filters, sparks, antifreeze, engine mounts etc cost me alltogether around 200 euro.
So to sum it up, the mod cost me alltogether around 1500 euro
... I never actually sat down and calculated all these
I could have done this mod A LOT cheaper. I could only change the cams and engine mounts.
That could have cost me around 800 euro but I wanted to do a propper job
as if it was worth it or not, I cant give you a final answer yet, as I'm still running the engine in for another 500 khm's .
What I can say is that its already showing its prospective and I'm very pleased with the result
.... at least I didnt have to pay for labour
