Cliff notes: I ripped apart my car, cracked intake mani, bad valve seals, bad valves, reground the valves and valve seats, ported head and exhaust mani, put on new flywheel all in a weekend. Works perfectly, anyone need this done or want help doing it? Pictures at bottom~
So last Thursday I get this bright idea when I was at work to rip apart my car. So when I got off work I tore it down, ripped everything apart to find out why my compression is somewhat shitty, plus I knew that I had leaky valve seals.
As I was taking everything apart I noticed the #4 cylinder runner on the intake manifold was cracked. The crack is all the way around the runner. I checked the how true the flange was when I put it on and it seemed just fine, maybe it was warped or maybe I warped it. Before I put it back on I had a buddy take it to his work and mill it flat. It was majorly warped so I have a feeling thats how it cracked. So I took it into Winona Weld and Sandblasting where they welded it up for me for $19, not a bad price at all and they did excellent tig work!

So I got everything apart and pulled all the valves out and find a couple valve seals shreaded which would explain why I was burning a little oil on start up and when idling for awhile.
Well I figured while it was out I'd go ahead and do a valve job to see how the machines I have work. I bought the valve grinding machine and seat grinder from Mike @ QPR about 3 months ago because he said he was upgrading. Little did I know that he was lying about that and really quiting the business.
So I grinded the valves and grinded the valve seats and they fit perfect. While doing the valves I found 4 exhaust valves that were bent very slightly but probably enought to effect some performance issues. So I replaced them and all it is good now.
Ended up doing a little porting on the intake side of the head just to clean it up a little and knife edge the little divider in each port. Ported out the exhaust manifold as best I could to hopefully gain some extra flow.
Picked up a Fidanza flywheel from a guy on the site here so I decided since I had everything apart I might as well put that in too. Damn thing is so light, I am loving it!
Hot tanked the head, made sure it was all cleaned, put new gaskets and seals throughout the top end and put the car back together. Runs perfect, and seems to pull a little harder. Havent done a compression test yet but I will tomorrow night. It seemed to help out a lot for just a weekend worth of work. Started Thursday morning and was done by Saturday night.
Here are most of the pictures in my photobucket album:

I have all the equipment needed to do this so just trying to help people out if anyone wants this done/do it themselves your more than welcome to use it at my place. Going rate is a case of beer with your help if the head is off the car!
Let me know what you think...
