Re: It won't stop...I'm helpless!

I like the Driven grease from Joe Gibbs like this: https://www.summitracing.com/parts/hrs-99005. It's available also in a larger size 1 lb tub if wanted. Isky and Lucas also have their own camshaft break-in grease as well. My humble opinion is what Comp Cams provides is good for the bearing journals but the lifter face and cam lobes do not get pressure lubed by the engine oil pump and must make do with oil splash from the crankshaft and whatever drains down from the lifter valley. Again, that's just my opinion.

I'm still not sure if it makes sense to install the new valve springs from qualcast...do you think I also should change the springs?

I don't think my current installed ones are too loose. This won't fit to the damages I've got. And they can't be too hard, cause they are the original ones from the stock heads...

Any recommendation?
Thanks.

Yes. Let's hope these are the last lifters and cam for this car for a long time...

BTW...what's about my question regarding the valve springs?

I'm not a good one to ask about the springs. But I'd think you should go with the new ones.

Although knowing about the bad material quality of today...

Good point. But at least the springs shouldn't be too strong, even if they are bad they should be softer. And replacing them later, should you need to, would just take pulling the valve covers.

Re: It won't stop...I'm helpless!

Yes, that where also my thoughts.

But I think, if I have to replace them, I'll replace the heads completely. The people from fullsizebronco tole me that the stock heads are not very good.

Replacing them was already a plan for the future...

Rene' that is correct, the first EFI heads for the 5.0L are some of the worst flowing heads Ford ever used. One of the upgrades in the 70s was to put 351W heads on, I seem to recall using special head bolts or some hardened washers as the 351 uses 1/2" head bolts and the 302 uses 7/16" head bolts.

Years ago I built a 302 up for the 1970 1/2 Falcon station wagon we had. I used a pair of 1965 289 4 barrel heads, and the matching intake, 351W exhaust manifolds and front section of the dual exhaust for a 1969 Torino 351 4 barrel, the remainder of the dual exhaust was for a 1970 351C 4 barrel.

My late wife blew the 2nd gear band on the C4, so I found a Windsor bolt pattern C6 and a slightly higher stall speed torque converter. While I was at it, a friend had a 1970 Torino wagon he was scrapping, power steering, front disc brakes, AC system and magic doorgate ended up on the Falcon along with the third row seat.

It's done! I'm opening a new threat, cause I have (how should it be different...) some new questions.
