Some big cleaning on the bowl today and a modification on the runners to increase tumble
The exhaust ports are really a mess and had very sharp angles every where
what a shit !
it was quite long but now the short side radius is very smooth on the intake and exhaust ports.
the larger path next to the valve guide have been increasd for more tumnle effect but nothing spectacular however .
I plan on smoothing a bit the boob bump of the guide to have a smoother transition between the brass part and this bump it will help i think.
