IIRC, there is something in the fuel system to stop/decrease pulsings, but I woldn't enev know where to find it.
I'd start from the source...er shop, and find out exactly what they did, what leaks they stoppped, how...etc.
Might just be a coincedence, but not likely.

Screw a gauge onto your fuel rail, and see what your pressure is doing. If it is pulsing, then you need to do something about it, if it is steady, don't worry about it.

i have a fuel gauge on the fuel rail alredy, it seems to jump around vary fast but onlu about 1-2lbs im not sure if it did this befor the head leak or not, all i know is there is a loud tickin from the back-top side of the motor and i think its the afpr cus i can feel it the best from there!! it never made this sounds befor the shop. they did have to pull both heads so the top of the motor was torn down!! could there be somtin stuck?
