Need some help on rebuild



I torqued them to the recommended torque specs when I had the engine on the stand. I'm using the felpro intake manifold gaskets also.

Oh no, this sounds allll to familiar! When you torqued the Cam, did you re-use the same bolt? If so, did you clean/thread lock it good?

I hate to say, I had this EXACT same sound then no start, came to find out the cam bolt backed it self out and now I'm on motor #2 :(

Take off the front cover and inspect your cam bolt and keyway, if you see any damage there, I feel your pain man lol.
 
No I used a brand new cam bolt from zzp.

I torqued the cam bolt on tight in an engine stand so there's no way it could have backed out and un screwed itself.

^^^^ So very correct.
The bolt I think is 75lbs plus 90*. You know why it is plus 90* because most engine builders don't have torque wrenches that go to that high.

This happened to one of our bonneville guys 95Nasta.(crazy engine build too not just a rebuild). I would pull the timing cover.
 


So I just self F it and went and bought a head gasket from auto zone and took the front head off to inspect. Check the entire head and everything seemed fine and the pistons also. I put the head back on and torques and soaked the lifters and added oil in the valleys this time.

When I went to tighten down the rockers...it seemed as though this time the springs actually compressed lower this time than before and not all are depressed at the same time

I need new lin gaskets and ive been busy with work so ill finish tommorow or Saturday.

Also the rockers before had play which I think was causing the tapping but this time NONE has play.
