Does any one have any valve springs or pushrods for sale that would work with this setup that will last?

You'd want to mockup your current ones & see what your preload is & then if needed buy or make an adjustable pushrod & find the perfect length you need then see if there is a readily available set for sale new, or used here on Moparts or if you have to order a custom set (Smith bros gets good reviews). On the springs one of the cam guys will likely chime in & give you a good recommendation live every 24 hour block of time like it's your last day on earth

In addition to what Robert said I would definitely check the retainer to guide clearance with that much lift especially if these are production heads. If this is a hydraulic cam you will need a pair of solid lifters to check with. It's easy to convert a pair of old hydraulics to solids if you don't already have some.

As others have said, springs and pushrods are a trial-&-error deal. Depends on installed height with your valves. "+" & "-" locks & retainers can provide more options. Head and deck milling will influence best pushrod length along with valve height. Typical 7.5" solid or 7.21 hydraulic pushrods would be a start, depending on lifter choice. Use good adjustable rockers.

My motor is built 30 over 11:1 compression and the valve reliefs are plenty for this cam. Im not sure if the crate springs will take the lift of the cam I installed

That will help in determining if and which replacement springs are needed. I don't know what pressures the OEM crate springs are, but something around 130-150 seat and 320-350 open should work. Coil bind and guide clearance need to be checked. I got to liking beehive springs (Lots of rocker arm clearance.) Here is a Comp Cams example, but again, gotta check your existing installed height & related measurements. These would also require locks. I don't recall if Comp has "+" or "-" .050" locks for them in your valve stem size. If your IH is under 1.75" it probably wouldn't work. * Comp Cams Beehive Springs 26918-16 - 125lbs @ 1.800" - 367lbs @ 1.160" - Spring rate: 373lbs/in - Coil bind - 1.100" * Comp Cams Steel Retainers 795-16 - For above beehive springs - 1.096" diameter - For 10* locks I know where you can get some if confirmed they would work!

Those springs will not work with Stock length 360 valves. Installed height with stock length valve is 1.68/1.70. As said before make sure to check installed height on the springs and you will likely need to trim the valve guides for that lift. You sure don't want the retainers to hit the guides or to have coil bind. Pictured the partial results of coil bind:

I run a lunati 60710 voodoo roller cam with comp 901-16 springs/stock retainers/locks/seals. lunati recomends the same spring for all of thier SB cams,they are doubes with damper/need machine work/seals the 901-16/stock retainers have worked fine with the 5 lunati SB flat tappet cams my club members run. the 292/292 in Roys 89 4x4 sounds awsome. they all have .485/.485 lift using stock valve gear. not sure if that will work with that much lift/1.6 rocker though. but comps are a cheaper drop on spring with the 1.5 rockers

For example, if your installed height is really 1.700 and your lift is 0.540 then you subtract the lift plus 0.060 from the installed height and your spring must coil bind at a shorter height than 1.100". Well, less than or equal to that. But if your installed height is 1.600 like my pair of 318 heads then you need a different spring. So measure your installee height and work with yor cam manufacturer from there. I think Hughes 1110 springs may be good in that application. 2. Spring retainer to valve guide/seal clearance is iffy at best. I think you'll end up cutting down the guides to gain the required space. R.

Remember tha tyou need at least .60 more clearance between the retainer and the guide/seal than the max. valve lift. and this is also true for the coil travel of the spring. You need at leas and preferably more than .060 more travel than the max valve lift.

So you measure the guides OD and get the cutter that's for that OD except if you want to put different seals on it. For example, my 302 heads had a 5/8" or a little larger guide OD and I wanted to use stock umbrella seals so I got a 0.625" valve guide cutter with a 3/8" pilot, chucked it into my Milwaukee drill, and with one hand on the drill and the other on a spray bottle of cutting fluid I did all 16 guides in about 20 minutes. Clean everything up, put the valves back in, used the little plastic sleeve to slip the seals over the stem grooves and pressed them down onto the freshly-cut guides. It was a piece of cake. Cutter cost about $50. R.
