I have ported stock iron heads with 1.77/1.50 Manley SS valves. does this mean that the valve guides have been machined down already? If you have bigger valves is this a required modification? I wasn't sure if this mod had to be done for bigger valves. When I get back home this weekend obviously i can see if they are machined for seals or not, but i'm away and trying to figure out what else i need to do to convert to a roller setup.
