I'll take a shot. I assume your using -135 film. You don't mention what your contrast filtration is but if it is higher than #3.5 you will enhance the existing film grain.
Your EI is fine. I shoot this film at 80 with D-76 1:1, 20c with a development time of 10m. My small format enlarger is a Leitz 1c which prints between a condenser and diffuser. HC 110 I read separates mid tones but will not shoulder off the higher zones as D-76 1:1 would.
D-76 would be a better film developer unless you are experienced. A standard technique is to view newsprint through the negative. If enlarging with a diffused light source you should have difficulty reading typed text through the dense portion of the negative. If highlights are blocked you likely over developed.
Enlarging -135 FP-4 with a dichro head to 8x10 I don't experience grain in the sense you can notice it. I develop -135 in D-76 or XTOL 1:1.
