That pretty much describes my situation. I’ve got the original EQ’s, with stock length and size valves w/lift limit of .540” springs etc. No actual real porting, only bowl, seat cleanup and guide boss reduction/teardrop shaping, gasket matched. To go with a much bigger lift cam I would have to buy new valves, springs etc, send out for professional port work and the valve job. Adding it all up I’d be better off getting the TF’s, cleaning up the EQ’s and selling them along with the rockers etc to recover some of the investment. Oh, and I’m also losing about 50 more lbs on the front of my vehicle so that’s what I did :thumbsup:
