Pushrods

First,you should not be bending ANYTHING with a cam that is a "bit hotter",that is
job number one to find out why.How much lift?With a ported head surely your
machinist would ask that and be sure the retainer to guide clearance was OK for
the cam.Second, exactly how much milling?Antything over .060" TOTAL(head&deck),
will make the pushrods very close to hitting the rocker arm at lift esp. w/extra lift.
You will need shorter ones,mopar used to sell cut to length chromemoly kits,but I
successfully removed the cups from a set of crane CMs and cut them down.It's
not likely you've got a valve/piston interference issue unless you've got long rods
and a much higher piston in the bore.The one thing about slanty's the stock piston
ht. is WAAY down in the bore,even mowing the head& deck usually leaves plenty of
room for xtra valve lift.You shouldn't be running much valve spring load for that to
be an issue either,it would be helpful for some particulars on your components.
Hope that gives you some direction,good luck and keep us posted:coffee2:
