New head fitted to white PI

One of the projects currently on the go is trying a new flowed head from Gareth Thomas. Humph had volunteered to spanner with me so we picked a nice 40 deg day in the tin shed to go head swapping.

The old witor valved and Luigi flowed head didn't put up a fight and was off in about 60minutes. Then it was a case of swapping the required studs, springs and spacers onto the fresh head and reassembly

Fired up straight away and after a quick retorque and reset of the valve clearances we decided that too much ale had been consumed for an immediate test drive - the hazards of working in the heat.

I will be roadtesting to check timing and fueling and then heading to the dyno early in the new year for a back to back comparison with the old head that made 123rwhp in early December 2011
