"And how about the valve springs i can use stock springs right??"
Yes you can use the stock units, if the pressure at installed hight is correct!

On a hydraulic cam when you preload the lifters, the plunger will change the pushrod position!

A 3/8" rocker stud has 24 threads per inch. You generally pre load the lifters about 1/2 to 3/4 turn stock setting, which will put the rocker arm about 0.021" to .03?" lower This needs to be considered as well. So your push rods should work fine! If the valve stems are equal length above the head!

You are building a basically stock flat tappet cam engine with a little more power. the demand on your valve train isn't that demanding, and the basic hydr. lifters are designed to compensate for minor differences in expansion, wear, etc. when hot your lash can change from .006" to .020" depending on component materials! The lifters will compensate for this if adjusted cold and when readjusted hot your push rods will be .006 to .020 closer to the rocker!

If you were building a full out race engine it would be more demanding on the tighter tolerances in order to stand up to the demand put on the valve train!

The rocker arm tip should be in the center of the valve stem tip at half its travel when opening the valve, when lifters are pumped up after engine is primed. The only thing that can make a problem with the push rods I sent you is : If the head was milled, valve seats installed and machined high, valve stem tips machined, different length valves installed, a thick head gasket, Cam grind,etc any thing that moves the valve train closer or away from the cam lobe will change push rod length! If your valve stem hight looks good in the pics you post: you will be able to run those push rods!

What do you mean with preload ... Leave them a night in the oil ? The picture where the chekker seems to fit is with a not fully load lifter i could press the pushrod a litle in the lifter the picture where the chekker not seems to fit is a fully load lifter. I cant pres it in The heads are milled a little. Valves are regrind but to compensate that. They grind a little of the valve stem .. The center of the rocker is touching the middle on the valve stem.. Like you see on the picture. .. To if its going to work Are the lifters getting pressed in a little ?

After they are installed and initially adjusted !!!!! After your engine is assembled When you prime the engine with oil, your lifters will fill with oil (load) "PRE" start up! Do you under stand what I meant by preload? I meant prime! Sorry!!

Yes your lifters are collapsing a little.

The tool touching the push rod and valve tip is perfect! the other is close

The Weiand X-celerator will match your rpm ranges better then the torker with that cam and the 650 should work very well on it with some minor initial tuning!

The push rods should be fine when you adjust the lifters! I need to see the straight edge across the valve tip pics. Then we will go from there.

Wezz:

When you install a carb, there is an initial tune for idle, mixture, accelerator pump squirt and duration, secondary timing ETC. just all basic tuning when you first install a carb! every engine has different demands!

There is a list # on the choke horn if its a Holley, post it! If its a 650 it should work fine with your build

You already adjusted the lifters? OK, that's fine if they are all running on the center of the valve tips you will be fine. Finnish your assembly
