Well the heads are off.

I have not tested the intake valves, but checked all of the exhaust valves, for leakage.

As you can see, they very much correspond with the bent pushrods.

and the previous leakdown test;

Leakdown

#1 16% retest 18%
#2 5%
#3 26% retest 14% (could have been a leaking fitting 1st time)
#4 8%

#5 5% retest 4% (this was the last cylinder to be retested, just to verify the numbers were meaningful)
#6 18% retest 12% retest 10% (could have been a leaking fitting 1st time)
#7 5%
#8 12% retest 9%

As you can see by the photos;



Number 6 and 8 exhaust valves are pissing

and on the other side;



Number 1 and number 3 exhaust. Number 3 seems to be the worst, on this test.

Sorry about the shadow, some close ups;




The test is supposed to be done with brake cleaner or kerosene. I had paint thinner which is close enough to kerosene.

So decision Monday, if I send the heads out to be CNC'd or just fixed.

Pistons look fine. Nothing kissed any of them, so I am assuming not stiff enough valve springs on the stock edelbrock heads.

It'd be awesome to get this all back together soon, but I know the summer everyone is damn busy, but we'll see after I phone around.
