anything hardend that are one piece style should be pretty good. the "*****" on the end are welded in and can pop off. the one on the left is a stock style, the one on the right is what you want.... i dunno exactly what style that one in the middle is LOL but i looks like the ***** are welded. did thumper cut down the rocker mounts and tap them for screw-in studs and guideplates? i really hope your not running a bolt down rocker with a huge *** lift cam

jesus lets see if i remember correctly..... the installed vavle stem hieght is something like 2.157 - 2.187 for BOTH intake and exhaust. the pushrod length is the same. what lift is this cam and what kinda spring pressures do you have where you would destroy stock lifters? if your going something that ***** out i would certainly suggest GOOD thickwalled hardend pushrods.
and pushrod length has nothing to do with piston to valve clearance, rather it is determined by the correct valvetrain geometry. the lifter must have some pre-load but not be bottomed out when the rocker arms are adjusted. (i sure hope you have screw-in studs and guideplates on these heads with the crazy specs your talking about). if they did your heads right, the stock length SHOULD be the right size where everything can be adjusted properly with your setup.

hes looking at aftermarket heads isnt he, i was just letting him know because im running holley systemax heads and the pushrod length is no where near stock length. once again thats with a pedestal mount setup. thats why i added that above and i stand corrected my brains not running right,i meant to say piston to valve should be checked before head installation. pushrod determination by top dead center. its getting late need some coffee sorry

RE: push rods
If you are getting stronger valve springs i would suggest getting hardened pushrods. Trickflow has a one piece hardened pushrod that isnt too expensive, but you should check for correct pushrod length.
