FE Technical Forum / Cut down 427 "tulip" valves in a 428CJ head..
« on: January 21, 2022, 02:19:54 PM »
I think I remember that the CJ head liked a "flat valve'' and a tulip valve hurt HP . I have a set of XE valves that appear to be 427 MR's cut to 2.095 and they have a 45* seat , not 30*. Before I cut the angle in my otherwise unmolested 68 heads I would like to know if it's a good move. I could always cut the valve to 30*s as there is enough margin to do so .
Thanks ,
