you need to buy a push rod length checker to find out your length you need.
try http://www.northernautoparts.com or 1-800-831-0884 they have comp cams magnum checking pushrods there are 2 different ones one is individual length checker part #7901-1 messures 7.5inches - 8.7inches $12.99 and the other is a whole length checker kit part #7900 6.125inches - 11.5inches $54.99. or you could borrow one from someone you know has one.

With a roller cam you will need .080 wall push rods.
If you shop around you should be able to buy these for about $100.
I can just about bet you will need +.100 long or +.150 long to make it all work correct.

Don't assume or guess the length. Measure it. With the lift you are using, it is very important to the rocker geometry right. If not, the valve guides will be crap in very short time. Not to mention if the roller slips off the stem.

I run the Comp Hi-Tech series pushrods due to the spring pressures of the solid roller.
