Question About Pushrods!

I just put my heads on and my cam in and i need to figure out what i need for pushrods! My Heads have been milled .010 and theres a new cam in the motor. Im getting new pushrod either way, dont want to run the stockers. Do i need shorter pushrods or will stock lenght suffice? I have an adjustable pushrod that i used, i assembled the valve train and put it in there.. with the valve all the way closed it seems like i ned a .050 shorter push rod. thats the measurement me and my dad both got. My dads friend who owns a shop measured and said he thinks the stock size is right.. anyone have any input on the matter? thanks!

I think the stock ones would be great. Alot of guys will mill their heads up to .030 and still run the stock ones and it seems to work fine. Thats my opinion!

Stock pushrods will be fine unless you want to switch to hardened pushrods

Use a black marker and see where the roller is striking the valve stems. Compare the stock length with the adjustable rod and see which gives the best striking pattern. That would be the best geometry. JMHO
