Pushrods Length

I have searched this forum top to bottom using every search word I can think of, but haven't come up with an answer.

I have a 95 GT. I bought a set of GT40p heads that have been fully rebuilt with aftermarket valve springs, pocket porting and port matching done (this is from my Father-In-Law). Can I use stock pushrods with these heads with an E303 cam? I've heard yes and no onthisdo

TIA

Jim

I would measure plus I would want hardened pushrods as I have seen stock ones bend.

You have to measure. People are not being asses when they suggest that and you'd be amazed at how many ppl take it that way on this and other forums. You need:

-Solid checking lifter
-Adjustable checking pushrod
-Digital Calipers
-Sharpie

There are plenty of how-tos on the interwebz (youtube) on how to properly check pushrod length on a pushrod motor.

This is why I install studs and use stud mounted rocker arms.

I used stock length push rods on my 94 5.0 build. I used 3-Bar GT40 Heads with the E303 Cam....So I would say the stock push rods should work on GT40P Heads too. You do want Hardened Push Rods. I hope you upgraded your Valve Springs too because they are too weak for even a Stock Mustang H.O. Cam.

Did you check the witness marks? How do you know you arent putting extra wear on your valvetrain from too long or short rods? You HAVE to measure to do it right. Period.

Install a solid checking lifter with the intake off, install a clicking type adjustable pushrod and mark the valve stem tips with a sharpie and go. Very easy. Only bad thing at all is you have to wait a few days for the pushrods to ship to you so the motor will be down for a week or so even for a simple can swap. Unless it turns out the stock length pushrods are good lol.
