POPOs TOP END build thread....
So after discovering a busted valve spring on my stock "ish" Lt1 heads.... I jumped in with both feet, after a fello member pointed me in the direction of some beautiful heads....
Lets start with a pic of the BROKEN.... (I know its small)broke.JPG
We also, just made the assumption that the valve may have bent, but BLUEBOTTLEZ can explain that.....

So the plan.... GO BIG, or GO HOME.....
I was pointed in the directions of these:
http://ls1tech.com/forums/parts-clas...ds-1126-a.html
At $2300, they were much cheaper than the near $2700 price Ive been seeing......... and they are still new....never installed.

THESE ARE THE 1126s..... Race ready, CNC'd, yada yada yada..... (as you can tell Im excited....)

Then people started telling me, I needed the LT4 intake..... So I asked him, and he had the edelbrock "air gap" LT4 intake.....

I purchased the heads and intake for a savings of about 500 bucks shipped, and its all new.....

Trust me, after PARRISH, Im very skeptical.... but, I continue to "trust."
I think I can reuse my LT1 valve covers, if I do some clearance work.......
Now, I need to start figuring out all my odds and ends....
-Shaft mounted rockers.......
-gaskets.....
-and a legit blower cam....
If anyone can think of the stuff Im missing, please let me know...... and if you have any suggestions for "decent" priced items on my odds and ends list.... also let me know......

Like I said man, we need to figure out what your compression ratio NEEDS to be and what it WILL be as is so we know if the heads need to be milled, what thickness gaskets you need, etc etc etc.
We need to know:
What pistons you have
What your deck height on your block is (if it has been decked)
Chamber Size of the new heads
Once we know all that we can figure out what else needs to be done to get your Static Compression Ratio to the right place. Once we have that where you need it we can get you a cam spec'd out that will give you a good low end, a great top end, streetability, and a good Dynamic Compression Ratio. Like I told you before...forget about getting "high dyno numbers" and focus on setting it up for that 1/4 mile...Then whatever you dyno won't matter because it will support the numbers at the track and on the street...
If you focus on getting big numbers, yeah it will be cool to tell people you have some huge dyno numbers, but when you go to race you could end up a dog at the track and losing to a lesser vehicle.

sounds like you got a good set up there.....i will still suggest talking to LE, AI to get a cam spec'd.

I threw in a few numbers into the formula for your Static Compression Ratio just to get an idea of where you are and this is what I got...
Bore - 4.040
Stroke - 3.750
Chamber - 65cc (Chamber size of the 227cc AFR Heads he purchased)
Pistons - -16cc Inverted Dome (I picked these because of his previous sub 10:1 compression ratio, not sure of exact size though)
Gasket Thickness - .026
Block Height - 9.015 (I chose this number because I don't think his block is zero decked but chances are it has had SOME work so I picked a happy medium)
With these numbers I came up with a 9.79:1 Static Compression Ratio.
This will vary and can be brought up or down depending on what you want by changing the gasket thickness, decking the block more (if possible), milling the heads, etc. Once you know the final details we can get that on point and once that is done we can focus on getting a cam set up that will get you a good Dynamic CR and make this thing a monster. Also look into the lifters and find out what you have in there...depending on what they are they may need to be upgraded, then pushrod length needs to be re-measured to ensure you have the right length in there.

Is it possible to use the stock valve covers with shaftmount rockers?

Ive heard you can trim the baffles in the stock valve covers to clear bigger rockers. I havent ever heard anything about shaft mount though
