For some odd reason we have had 40 degree days in Nebraska so I just had to pull the car out and did a few pulls. Second one car died. Started up and was running rough. Checked timing first that all checked out so did compression test. Front cylinders were 40 less than back. Use to be even within 5. Pulled front head off first found head gasket was bad. Also some of the head bolts were little looser than should of been. Looks like bolts are stretched causing head to lift under boost. After removed back head found it was broke where mani bolts up. While got it all apart doing full port polish cams/gears, and valvetrain then bump redline to 7k. Will be posting pics of the progress.

 

how did u determine that the head gaskets were bad?? Ive never stripped my car dwn that far, only just to do fuel injectors, is it that much longer to take the heads off and see which one of my valves were bent?? Trynna swap in good heads so I can get bak up and running.

 

Well I knew I had a big drop in compression. Been wanting to build heads for sometime now and figured this was the time to do it. They had to come off anyways. Once I got them off it was clear front one was shot. Was glad to see gaskets not valves or ring lands broke.

 

Sounds like you really lucked out!!! How much boost you running?

 

I was on low boost around 15 will be running in 20 range this spring

 

Been a little slow on getting this done waiting on parts etc.


Intake ports

Exhaust ports Bad picture of them

Before lapping valves

After

Schneider dual valve springs. These are best can get for your money. Will be bumping rev limit to 7k
All assembled and got heads decked.


What I do for a living.

 

Good Luck on that and very Nice welds...

 

Hands down the cleanest welds I've seen in a loonngg time. Looks sick!

 

Shipped my cams to to Schneider they got lost in the mail!!! Found another stock set on the Z31performance they should be here Monday then ship them to Schneider...stupid me for not get tracking number.

 

Finally took one month to get my cams regrinds from Schnieder. Cams lost in mail bought set online shipped to them directly and only sent two right hand cams. Put heads on today got far as I could before I had to go to work.

Russ Cam gears(yes the are pink suppose to be red)


Can see how much the took off the base circle. 280h grind.

Tomorrow plan on doing timing, headers intake charge piping back on and few other little things and hope to fire up.
