The .125 size in the 2nd hole might be too large. Might want to scale that back to the .092 since you have that size bit.
I'm not sure on the 700r4 accumulator valve and it may be different than the 2004r. I do know the trick for the 2004r is to replace the linebias valve with a stiffer spring and put the line bias spring in the accumulator valve. At least that is what I am doing.
