Which Lunati cam did you recommend?
Been where the OP is many times and spent good money chasing my tail and not listening to good advice (my experience).
A couple of options stand out to a poor boy like me.
1) Pull your heads and send them to PRH or call Hensley Racing in Tn(closer to home) for some quality porting and valve enlargement and put a set of 1.6 rockers on it (at least the intake side).
2) Buy a set of Edelbrock heads and have PRH prep/port them for you and go with the same 1.6 rocker setup to get a little more lift out of your cam for the better flow.
Both ways offer a "budget" level of upgraded performance that you will feel.You can always change the cam later if you feel froggy.
