If you go too big on the chambers you start screwing with velocity and throttle response. Larger heads would only strengthen the setup from 4K+, IMO. (Where the smaller heads get outdone due to runner sizes.) I would opt for nothing larger than 215cc myself. Good job to the OP and Patrick G for making things work right, once again.
and pewterscreamin, my car feels very nice on the street! today I made a pull from 2500rpms, it just pulled like No problem!

That is a VERY stout engine. I love the graph and the #'s are very nice.
That is exactly what I would be looking for as my next motor for the Z.
Congrats and enjoy it!

In a couple of months I am planning on porting my FAST 92, getting a larger lid and getting 1 7/8 headers... Then we will see...
until then I need to race this car to see what track numbers Im gonna put down(but before I must deal with my sinking clutch pedal)
edit: Oh and this is with Harland Sharp Rocker rebuilds

DAMN! EXCELLENT numbers with such a small cam/headers and through a 12 bolt!
You have another 30-50 ponies to pick up with the little bolt-on/port upgrades mentioned in this thread

the gasket was .040 or .045 I believe
The pistons were -10cc... I sanded out the rough edges on the pistons though... so that lowered the compression a VERY minute amount...

I didnt have my AC belt installed at that point and I do have an aluminum FW and 25% UDP and my DS is also aluminum... So all of that im sure helped as well...
But Im still gonna get a larger lid, maybe so Ill port my FAST 92 and maybe change the headers to 1 7/8
does anyone know the weight between pacesetter 1 3/4, TSP 1 7/8 and Kooks 1 7/8 headers??

I think they were 63cc from TSP, and they were probably milled .002-.003 the most after that, when I had them checked for bent valves and the valve spring installed height..

it is still nice to know we can put together a combo like this, like yours, and that it works fine.
i have an LS7 clutch waiting to go in, so, that would take away some power. it's all good though.
my kooks ss stepped headers are not heavy at all. if that helps any.

My tune is completed for now...
Idling issues are almost done, Im gonna just leave it alone for now, it sometimes needs a bit of throttle on startup to stay alive, then it quikcly learn sitself..
on a downhill when I take it out of gear and press brake and clutch, it dies most times. but its not that bad. sometimes it doesnt even die anymore, just the idle drops , but it finds itself back up to normal idle rpm (about 1000rpm now)
