Idk about gently I had to use force.. my spark plugs were still in… once I get the cams out I will see
Do not guess, do not use Google or Yewtoob, and follow this procedure to the letter.

Ok cool so how do I get my valve to stop hitting my piston? Take the chain off and rotate the cam fully untill the time mark is back facing up?

Looking at the manual I can already see my driver side head is missed time…the timing mark was point up when I install the chain… it’s all the way to the right in the manual… so I just need to take the chain off spin the cams maybe like a full 360 then set the marks and reinstall the chains?

Yes. You need to start over. Remove the tensioners, guides and primary chains. You may have to rotate the cams slightly, and then the crankshaft to prevent them from hitting/binding. Then begin with the "Installation" portion of the procedure. You start with the drivers side chain. Crank sprocket keyway at 5 O'clock, drivers side exhaust cam mark is roughly at the 4 O'clock position. Make certain that the colored links match the marks on the sprockets, then follow the procedure. Once both chains are on and the tensioners are set, always rotate the engine by hand several full revolutions to make sure nothing hits

Do I need to remove my cams for that or can I just spin them to get it back on timing
Actually if I was doing it, I would remove the cams, pressure/leak check each cylinder and if all looks good. Follow the cam install procedures. It's an expensive engine not to be 100% sure it's OEM correct. Good luck

Me I decided to do it myself… I’ve been doing everything else so I decided to do it myself and see if I could take on the task.. I put on my headers by myself which was a pain now I’m doing the OPG and sprocket and blower

I would remove the chain tensioners, chains let the cams go to neutral. If I could not rotate clockwise freely, I would then take the cams out, but, you need to verify you didn't bend any valves before you go through cam install procedures which include installing the chains and timing etc.
But some on the forum said just to take everything off a against rotate the cams back into the right timing position and put everything back on… no need to go deeper into the engine

I just edited my reply due to the uncertainty of valve condition. I would remove the tensioners, remove the cams, pressure/leak check the valves. If all check good then do the cam reinstall procedures.

You do not need to remove the cams. Get the timing set up correctly. If a valve is bent, you will see that on a compression test.

As long as you did not try to start the engine with the timing fooked up, there should be no damage to the valves.

Everyone has their own opinion as to what works best for them. For me, The engine is to expensive to not do a thorough inspection and checks. For me, A compression check wouldn't be the best way to go to find a slightly bent valve. Its a good quick check for overall cylinder condition at a race track, but not the best for checking valves and valve seats. That's just me

Yeah I get what your saying but if I spin the cam back to

Yeah Exactly what I was thinking just put the chains back on try to spin it if I can rotate fully a couple times then it’s fixed if not then then a valve probably bent… other than that if the piston is hitting a valve it’s just means I need to correct the level of the valves by resetting the timing on the cams…correct me if I’m wrong

If the valve is bent I wouldn’t be able to spin after the timing correction just jumping straight into that will be waste if it’s not needed.. I’ll rather spend 5 mins doing that than 45-hours checking valves

Well at the end of the day, its your decision as to what is best for you. Everyone here provides their opinions which is great to help with what direction you should or might want to go with. But at the end of the day, Its your decision to make. I will admit, I am very anal with perfection, and attention to detail with everything I have or do, But I also know that does not mean that is what's best for someone else. lol Good Luck and post what you find

Also a good idea is to compare the marks on your new crank sprocket to your old crank sprocket, Count the teeth in-between the marks and compare them ,they should be the same . There were a few bad batches that came marked wrong from Boundry awhile back ,I assume this issue was corrected pretty fast by them though. I didn't see what brand you installed with the oil pump but it is worth checking !
