springs measure roughly 39.35mm ish across.

not sure if you want them measured another way

that sounds like the big ones which is encourging, so it sounds like maybe TWO things went right today  . there is only 2.85 mm difference between the small springs and the big ones . the small ones are around 36.5 mm.

you can also take a piece of manilla folder that is 2 inches by 2 1/2 inches and cut a square section out of the long side that is 1.550 inches wide and 3/4 inches deep and put that over the top of the spring and it should fit perfectly.

if those springs came on those heads from dart, you are definitely in business . if the "builder" bought the heads bare and installed them, it is impossible to know what they are.

i go by actual numbers, not by "they match the cam", because one persons idea of the correct springs and mine are not always the same, but as i said earlier, if the car revved to max rpm ok, then they are fine.

i have no idea what you are talking about but do not remove the oil pan yet . . remove the  bolts that hold the bottom of the toming cover to the ol pan then remove the other timing cover bolts then remove timing cover

The timing cover has screw in studs on the bottom, 2 either side of the crank unless i drop the pan down far enough i cant get enough clearance to remove the cover because it hits on the bottom of the crank.

Pan needs to drop a good 10-15mm at least. The whole engine has these screw in studs and you just put the nuts on.

Just drop the pan it will have rtv silicone where it interfaces with main caps most likely.

I can move the cover easily just can't get it off without by the looks of it dropping the whole pan or at least undoing all the nuts just enough to hold the pan without it coming completely off.

If it just had bolts, happy days it will come straight off.

Can't you take out some of the studs ? .  Put 2 nuts on a stud and tighten them together locking them against each other ,then undo the nut closest to the sump/ pan and the stud should come out .

you need to tighten the two nuts together pretty tight so they dont just spin on the stud . you would then turn the nut that is closest to the pan  but in your case the studs should not be  too tight therefore you can torn the  outer nut . . take a close up photo of the timing gears . there should be a tiny mark on the outside of the gears near the teeth . thiese marks must be perfectly aligned .m . if they arre not .m rotate the crank slightly until they are . . put the  trans in neutral to do this . . the spark plugs must also  be out . . after the marks are lined up see how much deflection or chain stretch there is . . then remove the cam bolt and use the instructions i posted to carefully remove it . . dont forget to buy a long bolt to screw into the end of the cam to remove and install it with .m . if you damage  a cam bearing you will bne disassembling the entire engine . . this is the most dangerous part of the pocess and the sharp edge on the side of the lobes casn easilygouge the bearing if it gets dragged across the  bearing . . .  sm

remove the plate that holds the cam in then clean it then post a photo of both sides of it . if  there are any marks on  itt replace it . .  after removing the cam gear take a photo of the back side of it also m. . after removing the cam reinstall the plate and cam gear on the cam and  lightly tighten the nut bolt  then stand the cam straight up on a bench then use a feeler gaugee to check  the clearance between the cam and the retaining plate write  this measurement down and tell us what is is also.t

Ok, I will be around all day to help confuse you and the Geritol set will also chime in after they get up.

All jokes aside for [for maybe 30 seconds]. There are NO stupid questions . The problem is effectively communicating exactly what the question or problem is . The damper puller is a good example of not really making your point clear.

This job is incredibly challenging and you can EASILY fuk your engine up . This is why I am trying to be adamant about some of the things you need to do . It really takes a steady and skilled hand to remove and install the cam without F###ing the bearings up . I am confident you can do it providing you follow my previous instructions.

One secret is to remove it incredibly slowly . It may take you 20 minutes to pull it out and you will also get tired while removing it, so when you do, simply GENTLY let it go and rest for a few minutes . The cam lobes will only damage the bearings if you drag them across the bearings, however, it is best and safest if you can get the cam journals on the bearings before you let it go.

After the cam is around half way out, do NOT let go unless the cam journals are in the bearings, because at that point, the leverage of the cam on the bearings at can dent a bearing if the lobes are inside the bearing and not the journals.

Also, do NOT rotate the cam as you remove it.

Yes take your time and be very careful .  The cam can get stuck a little when taking it out . Use your left hand if you are right handed to support the cam as its coming out . Old flat tappet cams get sharp edges on the lobes but your roller can should be ok . Lifters out 1st of cause ,and check those suckers out and post a photo .
