MG F/TF To radius or not to radius the exhaust valves.

I have my engine apart the new guides have been fitted she all sealed etc but my next question is that I have seen a number of posts on various forums re the radiusing of the exhaust valve on the edges to aid in the escape of exhaust gases.



This is a 143 VVC head I have cleaned up the inlet and exhaust tracks had the seats recut with 3 angle and new values all round.



Thanks
