OK here we go!

You said that you have tried 2 different heads and nothing changed
Probably not the head.

You did not answer this question

You should,.... A leak down test is a good idea, but i don't thing you will ever buy on.

now let start with the vac. gauge.
I'm trying to get you to loosen a couple of bolts(half a turn only!) to see if the push rod is two long and holding up the valve while running.
With a vac gauge you can check this with out pulling the valve cover.
It can also tell if you have a vac leak causing a cyl to drop or not fire.

buy on, and i will show you how to use it for this and may other things.

Now for the volt ohm meter, a spark will still jump or spark out side the motor. but when under compression, it WILL NOT. if the plug wire has to much Resistance, the voltage will not be high enough to to fire the spark plug inside of the motor.

Now here is some stuff that I'm not so clear about so PLEASE help me out

#1 You said that you tried a hyd lifter on a solid cam or was it a solid lifter on a hyd cam????

#2 You said that you have the stock cam back in it now with the stock lifters...........did you install new lifter on the old cam or the original lifter back in the block

Now that i have side all of this: it will still cost you 0 dollars to pull the valve cover and loosen the back rocker shaft bolt on passenger side and front rocker arm shaft bolt on drivers side.

And just in case you didn't click on the link provide you.
I thing its is of value


Odd driver side, even passenger side. Attached Images


Happy holidays!!
Ok i see i missed a lot of questions here lol. No there is no rags left anywhere... I am using the original points and condensor, however they are new. New as in a new points style distributor, cap rotor, points, condensor, etc. I havent done the vacuum test because i dont have one yet lol. The auto shop is closed today for obvious reasons. I do have a voltmeter, but, in all honesty, im not sure how it works. :newb:

To your hydraulic question: I tried using a solid camshaft with hydraulic lifters.
And im using the original lifters on the original camshaft. Meaning, Im using the original hydraulic cam with the original hydraulic lifters now.
