How to Replace Valve Springs With Heads On - Rebuild the 289 Ford - Part 13

Today at Alf's Mustang Garage we show you how to replace valve springs with the cylinder heads mounted to the engine. We have new comp springs that are tailored to the specific cam shaft we used. Whenever you change camshaft profiles, its best to select s specific valve spring that will best compliment your specific camshaft.

Hey awesome video! I have a question nobody seems to be able to give me an answer to. I bought a cam for my 1991 351 windsor it has .493 intake lift and .5 exhaust lift. My question is can i use the stock rocker arms and push rods or do i need a specific aftermarket set?

[ElSob]

Does it work the same for a Chevy 350?

Great tip! Compressing springs is always nerve racking to me - tons of potential energy in there.

4:40 put it down in a coffee can or something similar when releasing tension and do not have a direct line of sight from the spring to your face. It it slips in the tool and "springs" out, it can do a human body a lot of damage.

You can always check with a screwdriver too (with the plug out on the cylinder) to see where you are at with the piston height/valve clearance...

Old trick from 60 yrs ago:
Find tdc. Roll piston down a little.
Push a 1/4" cotton rope through the spark plug hole, roll the piston up to holdd the valves closed.
About 2' of rope will do it, tie a knot in the outside end so you dont lose the rope. 🙄

Did these 351 heads have any modifications to the valve seats to accommodate for 1966 leaded fuel to more modern unleaded fuel or is that not an issue?

[Bowman]

What is the part number for the springs?

[brandonkristy]

Does this sound like a broken valve spring?
65 Mustang with a 302.

There’s a ticking noise BUT the ticking is into the exhaust pipe on that suspect exhaust port.

There’s no exhaust leak.

Also, that header tube gets a lot hotter than any of the other ones.

I stuck a stethoscope to the lifter valley and no ticking there. You can even lay under the car and here the ticking going down into the exhaust.

I’ve adjusted the valve train a few times but still does it.

When I went to rent spring compressor the guy told me best to use air compressed into cylinder with compression checker hose to air compressor .
