bending push rods

the problem I have is strange-about a month ago I put afr heads and comp cams roller tip rockers on my 347 with a voo-doo cam well it did ok for a while then it started to tick a little so the tech at work that put it in adjusted the rockers and it did ok ,now if you adj the rockers it will be ok for 10 minutes and then it starts bending pushrods-we are using comp cams push rods-the heads are 165cc non emmissions heads -any ideas?

What wall thickness are the push rods? if they are not .080 i would say the cam and springs will bend the .040 or .060 wall rods.
Make sure roller rockers are centered on teh valve stems.
Maybe after it gets hot guides are sticking?

Not sure what model number push rods your using, but they should be Hardend Pushrods for the set up your using.

If they are, then you may have a coil bind, or pushrod length issue.
