Ok since dropping the boost and fitting a better blower, even at 20lb of boost, its just lifting the head and spewing its guts..... Its strange because with loads of boost/advance I only ever had issues with conrods failing.
Have regularly checked the rods by dropping the sump, and checking they all slide side to side freely... was all fine with 28lb on a stock DHY. I only have head issues.... awaiting on some new rods, and then I can fit these uprated head studs I have
As I live next to a field, I do like the odd ragging session, managed to snap this which I thought was quite good too... nothing like an Airey creation, but you get the idea
