I checked one of the combustion chambers tonight.
A 1/8 piece of clear acrylic plastic with a hole drilled in it. Used some Vaseline smeared around the bore . Pressed the clear piece over top and started adding ISO with some green food coloring . I simply used a 10ml syringe and started...
Well I have one head all done and back together. Leak checked them with some isopropyl alcohol and every thing stayed dry . PHEW ! Haha
Starting to compile my list of gaskets I need for putting everything back together. I think in going with the fel pro 8519 pt1 gasket Im pretty sure that's...
For anyone wondering , those are not the correct pins.... I didn't pay attention to the size... there were 2mm long haha exact shape.. but 50 times to small !

Got 90 % of the porting done on the one head. Just waiting for some 80 grit sandpaper rolls to clean up the rest of the intake ports I can't reach with the bits i have.
Used the templates, cut down a fair bit of the guide webbing in the exhaust ports , made sure that the short turn was a nice...
Picked up some lapping compound today and went at the 2 cylinders that had the leaking valves. The pitting in the one came out very quickly.
I lapped them and then threw the valves back in to test for leaks again. I had to do the one cylinder that was leaking the most , twice. But looks like...
I had done some basic clean up already . I threw few templates in to see where I was at. Good at 4 , 6 and 8 o'clock positions. The templates show more material to be removed at 9 , 10 and 2, 3 o'clock positions .
Well got the valves out. The cylinder that had the lowest compression has alot of flakey carbon . The other cylinder beside it that also tested a bit low, shows a bit of pitting on the valve seat. I quick wipe with some scotch Brite showed that thr pitting does not seem to be that bad. I think...
I grabbed the direct connection templates from my buddy today. They are pretty old and just made of some very thin plastic. I got on it right away and 3D printed a more durable and strong set
I did not. Before I pulled the driver side I did check a few bolts they torqued correctly . I know only checking 4 is not really very thorough but better than nothing. Are soon as break the bolts loose they could be take out with my fingers .
I will be putting are bolts in when I put...
Yup that's what I did. The sound i was looking for seemed more from valve cover , valley pan area than an exhaust port. When I put everything back together will make sure to use some decent graphite exhaust gaskets.
Did a quick clean up the heads with some carb cleaner , wire wheel , and scotch Brite wheels . I'm going to grab a valve spring compressor tomorrow and will pull the valves out and inspect the the two leaking cylinders and whatever else I can find!
Thanks
Thanks I always appreciate your input .

I was able to get the other cylinder head off tonight . Geez the passenger side is a PITA ! I was able to get it off with the header still in the car but feel I might have to pull it out when I put the head back on so I can actually TQ things down properly! Only one picture from tonight was...
What's everyone favorite way to clean up the heads . Get a Tupperware tub and go to town with some degreasers ? Obviously a parts washer would be ideal but I don't have one of those!
Made some more progress tonight. Got the passenger side head pulled off.
Have included some pictures of the lifters they all look identical.
When I was breaking the head bolts loose, they sure didn't feel like 70 ftlbs I was surprised at how easy they seemed to break loose .
When I went...
