First I bought lifters that I didn't need because the loud tapping sound I heard was two rocker arms that got loose and the pushrods fell off; then I decided to change the lifters anyways and when adjusting the rocker arms, I read the ft/lbs was 50, but that was for the rocker studs!!!! I ended up breaking all the pushrods on the driverside on start up and had to replace some of the new lifters with the old ones I just took off. I didn't know about valve lash until I searched online and started coming to the forums.
I was giving myself 2 days to do this job as it was the first time I was did anything besides clean the CIA; it was more like 1 1/2 weeks cuz I had to order and wait for new pushrods.

Launching!
acually it was a car the dealership had bought for an auto pronto (buy here, pay here). But no, i never found out why. It would spin to a point then stop, i could back it up and it would go a little bit then stop again. It wasn't the valves because i took the valve cover gaskets off and everything was good there. Maybe it was a spun bearing, the fresh 5w-20 might have made it let go.

I used the wrong kind of sealant on the back of my intake because I was in a rush and it ran down into the oil pan and sucked up in the pump. Once I put my 700r4 in and forgot to hook up the detent cable which in turn caused my transmission to blow up. Also I accidentally dropped a piece of a helicoil in the intake port of my head and it scored up one of my pistons. All this caused me to rebuild. That was a mistake I will never make again. Never rush your work.

after installing my headers, i was trying to fit my y-pipe in between the headers and my already installed borla catback. well got frustrated, started pounding on the ypipe with my open hand and sliced my hand off of the heat shield. needless to say my hands were covered in grease from installing the headers and i got 14 stitches at the hospital.
at least you took one for the team man !!!

volunteered to rebuild by buddies automatic transmission. How hard could it be, just remove the parts and put them back in the same way. WRONG... That was 4 days of hell and I couldn't sleep because i was worried about it the whole time.

Mine took a couple of days to track down.... Did a whole engine/tranny/rear end swap from my 94 Z28(RIP) to my 94 Trans Am(SOLD).
After starting it, it didnt really feel like it was idling very smoothly. It had open headers for a short while so it wasnt exactly the smootest car at the time anyways. Also installed a 3600 stall at the same time so during test drives the car was loud and started poping and backfire(thru open headers)! VERY LOUD!
Got exhuast put on, made it much quieter so we started to diag. the car...
thought it was the opti<<<(we always point the finger at the opti)... so I pulled the opti off and played with it, put it back together. Still did it.
Did that twice and THEN we check the spark plug wires! LOL!
FOUND IT!
The guy said that did most of the work!
And I swear not 10 mins later after leaving the shop my car DIED on me while pulling out of a lot...
THE OPTI WENT OUT!
