possible valve float??
I recently installed crane 1.7 energizer rocker arms and new crane valve springs. got the car running good and took it to the track last friday. it ran good 14.3 @96 mph. Well the other day i was messing around with a mach 1 and we droped and when i droped into 3rd the car back fired really bad so i just let off. then i heard a ticking noise. the noise turned out to be a header gasket that i just replaced. but now it seems like my car doesnt pull as hard as it was when i first got everything installed. seems like at 4800 it just falls off. yes i know on a stock 5.0 cam thats usaully where it falls off hard. but when i was running at the track it was pulling all the way up to 5200 at least. i do hear a ticking noise that has gotten louder than when i first had everything on the first night. im just wondering if i could be getting valve float or if that back fired had something to do with it or was it just random. thanks for any suggestions. oh and when i did the springs i got each cylinder to TDC the best i could.

i dont know i got them at a speed shop and the guy set me up with the springs to match the rocker arms. all i know is i spent like 140 bucks for crane springs. and got riped off for the price. i doubt any valves are damaged. car stil runs fine i just think im getting valve float at high rpms.

i did the best i could to set each cylinder to TDC when i installed the springs and rocker arms. my question is could something have gotten messed up. how often do you need to readjust your valves?
