I'm getting close to switching to a roller cam in the big block!

Greg: A quick an easy "rule of thumb" method is to take your assembled head, turn it upside down and fill the combustion chambers with water. If none leaks out of the intake or exhaust ports - they are likely pretty good.

No, the above method is not as good as lapping valves, as that will show you contact between the seat and the valves and where it is. If you are going to lap the valves, take a marker and put a line on a random point on the valve, extending from the center to the edge. Now put the valve in so that mark is at 12:00 position. When lapping the valve, only rotate it between about 10:00 to 2:00. Now when you pull the valve and check the marks, you'll know generally where you have poor contact (if you do).
 
Life happens, then you react accordingly.
I have to take a break from this for at least a week, maybe two. Today I was working on replacing a dishwasher here at home and when putting some tools away, a 4" cordless grinder was in my left hand, a few other tools in my right as I headed for the garage. I don't know if the grinder slipped out of my hand or what but I grabbed it by the middle and hit the trigger.....and tore a gash in my left bicep.
I had a long sleeved shirt on but the blade went in enough to scare me. I wrapped a towel around it and had Mary drive me to the hospital. Seven hours later, I was discharged.
I am one of the luckiest guys you'll ever know. They cut off my shirt and although the cut was deep enough to worry me, it had already stopped bleeding.
I was worried that I might have hit an artery or cut into muscle. Somehow, I did not. The laceration is perpendicular to the bicep so they cleaned it out, stitched me up, wrapped it and sent me to the pharmacy.
I can't get the dressing wet, dirty or greasy so that leaves car projects out. I may get the stitches out in 2 weeks or sooner.
No car stuff ???

Well if you were really lucky the battery would have been dead.

(Hope you heal up well my friend) :thumbsup:
 
Typing one handed takes a bit more time but…

Mary said it looks like a baseball stitch.

I have to wear a sling for a bit.
I am grateful though.
 
The rocker arm arrived today...

This has the LH offset to make up for this one...

It is slightly different. It has an oiling hole that the others don't and the adjuster is ball type, my others are the cup type.

It shouldn't be a problem, I'll just swap the adjuster from the spare RH rocker in the set.
 
For what it's worth. I'm refreshing the enging in my racecar. We vacuum checked each port with the springs installed. The exhaust valves passed, the intakes did not. After disassembling and cleaning the heads, the intake seats were dark next to the exhaust seat area. Another vacuum check without the springs installed, all failed. So there is food for thought. Using the liquid method on an assembled head will not tell the true story. At this point I couldv'e tried to lap them. Instead had everything touched up. It took about .006"-.008" on each seat/valve combo to get it correct. One intake valve had enough runout in the face that it was replaced. Another vacuum check w/o springs, all passed. I use the same method to install the springs. Head bolted to the bench with cardboard under it. Using two long headbolts in the center. You can get +/- .005" using the available .015" range shims. The height used on mine is 1.950". So the range is 1.945"-1.955". It got springs swapped in the car last year. They are 325/815 psi. You have to be very careful and have a strong arm.

Man, sorry to read about your injury.

Shop safety is something I am trying to get better and better with. I am actually now quite good at making sure I wear safety glasses, face shields, ear protection, gloves, etc. But I am not perfect, and it only takes a second for something dumb to happen. The other day I ground off some skin on my thumb because I got out of sync and didn't have my gloves on for a "quick second" while touching up an area on an oil pan I was cleaning. Of course the grinder caught a burr and bounced onto my thumb. Luckily, no major damage like you had, but things happen quick.

Stay safe out there folks!
