350 push rods
Hi all
I am instaling a set of edelbrock performer cylinder heads on a chevy 350, my question is with using the stamped steel rockers do i need to use push rods that are .100'' longer? Has any body run into this?

Do your heads have .100" longer valves? If not, mock up the setup and check your tip location.What if the "Hokey Pokey" is what it's really all about?

tip of the rockers seem to roll to the edge of the valve stem

Alignment problem, not a length problem. Guide plate on the heads?What if the "Hokey Pokey" is what it's really all about?

yea, iv'e got guid plates, i just found on the edelbrock web site that if using stamped steel rockers,to use +.100'' push rod and if yur using roller tip rockers use stock push rods, but how would the lenth help the alignment?

i would think .100'' is a big difference in lenth, could there be a lot of damage if i use them and there wrong? it could not push the valve open any more than normal because the adjustment would be less right?Last edited by Motown; 09-22-2007 at 03:50 PM.

Denny is bending over backwards here......the research has been handed to you....it's not our motor...it's yours...have you not dug in and gotten the arrow straight on your compass? As simply as anyone can tell you; do the geometry check and align the pushrod attack on the valve stem. Look, Look, Look, see what is going on we'ed all be to help, just need some solid feedback from your findings. Yeah, by the way "MUCHO" damage if you run it like it is. I't not far from being perfect, just some clean info to help you out.What if the "Hokey Pokey" is what it's really all about?

If the rocker tip on the inner edge of the valve stem you need longer push rods if it on the outter the push rod too long. The best set up is right ing the center when the valve is half way open.

Best way to know for sure what length pushrod you need is to buy a pushrod length checker, they're cheap and accurate... Takes all the guesswork out of pushrod length selection. All the cam companies offer one for sale.Yesterday is history, tomorrow is a mystery, Live for Today!

if the rockers are hanging off the face of the valve stem you need a adjustable guild plates or alot of them are sloted were the studs go thru move them were the rocker are on the center of the stem and lock them down. as for the push rods .i check them at mid lift so there is no guessing the rocker arm may not be true ratio or small or big base circle cam the deck heads height and the valves height set up with longer stems or bigger roller tips on the rockers will all throw off the true push rod sizeIrish Diplomacy ..the ability to tell someone to go to Hell ,,So that they will look forward to to the trip

Nw I'm confused, He said it's rolling to the edge. Stamped steel rockers don't roll, they wipe/swipe. Is this thing going off to the side of the valve stem or is what he's looking at actually the tip of the rocker contacting the valve stem during sweep motion?What if the "Hokey Pokey" is what it's really all about?

Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
