Lifted my heads off the race engine and took them in for a freshen up and a hike in Comp. ratio as allowed in the latest rules for F-Vee 1200cc.
The valve seats have been so heavily throated and cut so many times that by the time the seats and valve faces are re-cut, there will not be enough meat on the valve heads and the valves will drop waaay too far into the head.
This has resulted in having to replace all the valve seats, throating and re-shaping them again, recut the 3 angle valve faces and 4 angle valve seats and matching all the porting.................... One thing is that the seats can be reshaped to exploit the "venturi" effect.
Phhtttttt..... money money money.
The dammned thing was running just fine too!!
Oh well! You get that.
