I was all ready to order my heads tonight and ran into a few problems. I talked to AFR and they said since their valve springs are stronger than the stock ones I would need to run hardened pushrods even with the pedestal mount heads, even though it says on their site hardened pushrods are only necessary for the stud mount rocker heads. He said I need to measure to see what length pushrod i need, how would i go about doing this? I thought this was going to be fairly simple and now i am so confused, please help!

 

calm down....if you get hardened get trickflows...stock length....i ran stockers in my 185's for a while till i founf a set at a swap meat for $25 bucks brand new...so you are ok with what you decide

 

how can i be sure they're the correct length? I dont even know what size i need...

 

6.25 is stock but most go 6.30-6.6.35's for less shims.....

 

less shims? even with pedestal mount heads?

 

well i did mine that way so i could get the right installed highth on new springs...sorry..

mine are pedestal mount also..hate there springs.

 

sorry man i think i lost you. There is more to know about this than i thought...

 

do what i did...they worked fine...they advise hardened pushrods just to save there butt
on liability

 

oh and there valve springs arn't that much stronger than stock

 

they said the stock arent even 100, the standard springs are 120 and the upgraded ones (which i was gonna get) are 150... so they're a good deal stronger. Dont you have the 185s?
