Thanks mate that was my point.I have these heads and i wanna know how to make them work well and if they have worked well in the past.I know these are not the best heads to use for a 632 but thats all ive got to work with I am on a pretty tight budget being age 23 with a 632 Bracket car and no sponsers so every single doller that is used has to come out of my back pocket.Thanks for seeing my point.A mid to low nine will do me just fine and theres always going to be room to play with later on down the track.
