Why are we limited to the stock installed height? I dont have any heads here to measure, but is there not a +.100 retainer available that can be used to get to 1.76? Like does it physically interfere?
I do like the MP P5249464 spring, its what i have on my 587 heads now and I run them with stock retainers. Mancinis $10 option is way better than Summits $17, thats actually largely what started me on this quest cuz I have no problem running the P5249464 spring
