Hmm, that is a problem. It's extremely easy to get a tooth off on timing. It has a brighter link, but it's so damned hard to see. I always use some white out to make the marks on the chain. The bright link has to go on the crankshaft dot and the opposite bright link has to go on the dot on the camshaft wheel, and then it has to be tensioned.

First off, you are wrong! You do not tighten lifters. It could be a lifter but you would need to replace it.

Op, im curious why you used a 03 cobra block? there is no difference in the bare block itself. Also, why reuse the original oil pump? its a cheap part to replace and gives peace of mind. On the over heating issue, is the gauge reading hot and is the coolant overflowing? On the clutch, sounds like something was installed wrong

missed this post, more than likely, timing is off causing a world of problems.

Oh really? please explain how you would tighten them up

OP there are timing marks it just appears you did not take the time to do the job correctly
And you will get a little lash adjuster noise for a little while after a rebuild because they all bled down. If it is still ticking after running for a while than I would be concerned

I did time it correctly by what the haynes book says and u have a guy at my work
That says his clutch was out on backwards and it had a loud ticking sound so I have dropped the
Tranny and im going to reinstall the clutch and see if that does anythibg and
On the timing isnt it only one way you can time it because wouldnt the valve hit if wasnt
Timed right thats the probalem I had until I could turn the motor over freely with
A breaker bar

I would agree with Springer. Sounds like they are collapsing. Was gonna say the cam gear may not have torqued down all the way causing the cam to move back and forth but that sound definately sounds like the lifters. IMHO

I had a similar issue when I timed my passenger side head off by one tooth. It ran, not at peak performance, but it ran. And it was tapping really loudly. You say the timing is correct, but I don't believe you. If you had everything apart you should have changed the timing chains, tensioners, guides, and oil pump. Take the timing cover off and check again.
