What type of cam are you running? solid/hydraulic? If its hydraulic adjust it like you would the Chevys. Solids will have lash specs on the cam card.
 
You are probably running a setup very close to mine. Use the chart in Rumbles second post. To set the preload, tighten the adjusting nut until it touches the pushrod. This is where there is a difference of opinion. I prefer to tighten the adjusting nut 1/4 turn more then lock it. Some say that it should be a 1/2 turn. I just prefer a 1/4 turn. It's a little safer.

Rumble,s 2nd post?Get the coffee into you Jack.LOL:coffee2:
 
You should only have lash if it's a solid cam. The amount of lash is specified by the cam mfg. and can range anywhere from about .012"~.030". If it's hydraulic you need to preload it like Jack said although the amount differs by mfg. Some hyd. roller cams require up to .060" preload which with a 3/8-24 thread adjuster would be approx. 1-1/2 turns.
 
i decided to go against putting the 350 rockers in because i just got some w2 heads with pedestal mount needle bearing aluminum rockers but i havent decided to use hydraulic or solid lifters id need diff. rods for the solids
