383 engine noise

with 60 thou milled off the heads the intake had to have been milled or something for the bolts to line up...was the block decked as well? dads heads were milled .010 and the bolts were extremely tight to get in...but either different pushrods, or adjustable rockers I would assume are your only options. a custom shorter pushrod would be cheaper... I got some .080 wall Smith Bros pushrods for 200 bucks. throw an adjustable in there to get the preload where you need it and send it to them and they will make you a set right up

can't believe others haven't weighed in on this either, I don't have much experience with hydraulic setups but the fundamentals are the same lol.
