Use more than just GMs to bring up your hams. Try Glute-ham raises if you have one, stiff legged conventional, stiff leg sumo, GMs, RDL’s, hypers, and just basic leg curls, and even leg curls for time if you want. That worked well for me for awhile.
Thats the whole idea of westside btw, find weaknesses and center your assistance work around them
Whats your stats? Height, weight, best lifts.
Do a Westside Plan if you like, but I still don’t think you are ready to identify your weaknesses correctly and the best way to train them.
There are more to Squats and Deads than hamstrings…hips, upper / lower back etc
There will nothing happen’ if i just give it a try. 
I still think of how many and what supplemental/assistance excersices to use after the ME/DE ones.
This is the training plan that unstable gave me. I like it, and i’ll train it.
