Well i replaced the cylinder head again, this time everything has been re machined to be the tightest tollerance i can, re-routed all the water pipes and re-designed the cooling system. Fired it up and boy! what a difference, the car is a beast now, its running almost perfect, just need to finish these webbers and i'll be happy enough to get it back on the road for some final tweaks.
In the mean time during these lovely april showers i've been sorting out another improvement.
Aero on the front has been crap and as much as i liked the orange it had to go from the spoiler, so i have been re-making a new custom one from fibreglass.
This is the rough outcome of tonight, constructed out of alloy and fibreglass, its super strong, just needs to look a bit less bumpy

My first attempt at fibreglass and it shows. But there is a lot of matterial there so i will just sand it out smooth.
overall shape is just what i wanted.
only problem is what do i sand it with! angle grinder flap disk is too harsh, sander is not brutal enough, shape means most other tools are impossible.
grey is just a guide coat as it was 4 colours i couldnt see where to sand.
