LOL
They must have play to work. Normally .0015"-.003" for the exhaust, You should check the manual as that is just a rule of thumb. It is normal to see up to .005" on motors with 100K .005" is very hard to "feel" which is why you need an dial indicator to check them.

It is not a big deal either way. Your lapping will not hurt anything it just if you have more then .005" clearance it is not going to do much for you.

 

Oh okay. Well I definitely couldn't feel any play lol.

 

If you weren't blowing oil upon start up or while driving before, then I wouldn't worry about it now.
Besides, the last thing you want to do is put a set of nice tight rebuilt heads on a high miles lower end engine.

 

It smoked a little when I started it. But then again the valve stem seals were toast!

 

Could have been the seals, could have been the valve guides till heat tightened up the tolerances. You'll find out soon enough.

 

True this. Finally got one of my broke header bolts out. I broke the easy out off in the other bolt 0.o

So I have 5 out of 6 header bolts now. Better than 4 out of 6 lol.

I got the block cleaned up and ready to put the heads back on. Pretty exciting! Hopefully ill have it running by the end of the day tomorrow! Wish me luck.

 

Luck! Since you don't have the luxury of flushing the engine before assembly, here's a good crud catching trick that I've used, and it works quite well. Go to your sock drawer and pull out that pair of women's nylons that you've been hiding.
Cut off a chunk (double layer), enough that will drape over the upper radiator hose neck, with extra. Hold it in place while installing your radiator hose and proceed with the rest like normal. Take the car for an initial run, then after draining some coolant off the bottom, remove the upper hose. You'll be amazed to see what the nylons caught.

 

And nice idea with the nylons too.

 

To do the job properly, get the heads to a machine shop, do a valve job and call it a day...

 

Heads are already back ok the car. On to another issue now lol.
