360 la

im back guys...put a howards retro cam in my la360...cl713175-10...525 lift cam with rollers..used 98438-k32 springs on my 202 j heads..had the heads machined for the springs...the old dart runs hard but sounds like crap..valvetrain noise especially cruising around 2500 rpm..using harland sharp 1.5 roller rockers and smith brothers pushrods...got the preload on the lifters at 3/4 turn...the lifters stay pumped up well,no issue with them..but I dont like the noise...these springs have 122/353 pressure..will they be ok on a hydraulic flat tappet cam?...or is there anyway to quieten the sewing machine down,lol
