/6 head bolt + ring and bearing suggestions please.

I have another question for you /6ers that have been in these motors a couple times.

The cam on this engine... seems to have a whoooole lot of horizontal slop.. I can slide it in and out of the block close to 3/8 an inch..

This seems very excessive. IS this normal for these motors?

I do not even see a retainer or how these cams are kept in their journals on these motors. Do they just kinda free float in there and have the ability to move following the chain on the crank being retained by the chain and lifters?

Thanks again for all the infos!

Enjoy the nice days!
Likely the timing chain is worn. In use the oil pump drive gear and the distributor drive gear as well as the lifters limit fore and aft movement of the cam. Most racers add a cam button to the timing chain cover to positively keep the cam back.
The grime and sludge in the motor is from the engine oils that were in use in the 60’s and 70’s. Engine oil today is much better.
