So using ghost cam ( above)
.40 comet gaskets
fast intake
long tube headers
clean up heads
oil pump.
water pump
timing chain
sounds Like the plan
More questions : sorry
1 should I do porting or no
2 should I use oem oil pump
3 replace springs and push rods
4 when does it Become reasonable to buy new long block

this is a lot to ask, I realize but only because you’ve done so many of these motors I’m wondering if you have part numbers for these things.

thanks for all your help
I don't know what a valve job and clean up mill costs. You will have to check on that. I do know what TX Speed will do for $850:

Disassemble your heads.
CNC port your heads
Competiton multi angle valve job. I believe that is done CNC also.
Mill your heads from just a cleanup to as much milling as you want.
Clean your heads
Assemble heads with your valve spring of choice (you can either supply your own or buy from them).

What you get back is essentially an as new set of CNC ported LS2 heads. They look like new other than the machinist's dye around the valve seats. They are ready to bolt on. With better heads, you get more power without negatively affecting manners or efficiency. Win/win in my book.

At 100K miles, I would replace the oil pump and timing chain. A stock OEM pump is fine. Replace the cam sprocket. Replace the crank dampener too. I would also replace the water pump while you're there.

The only time I would consider a new long block is if my current one wasn't fixable.

The guys at Summit can fix you up with all parts needed for this build. You'll have to have whoever assembles your engine measure for push rod length. I'd bet that stock length would work as the valve job will "sink" the valves in the head about .010 (needs shorter push rods) and the cam will have a smaller base circle (needs longer pushrods). Best to measure though.

How hard is it to install those long tube headers

It's cake if you have a lift. Maybe someone will chime in who's done it on ramps or jackstands.

Can you say. Roughly How long would it take a shop with a lift to install

Is there a tremendous benefit to doing the headers while I’m doing the rest of the work or could it be done later without making a lot more work for myself?

We did a lot while it was up on the lift. Complete exhaust system, sways and shocks, ran the vac line for the bi mode Z06 mufflers, etc. All work was done almost 6 years ago also. Can't really tell you how long the header install took. I did have everything there to complete the entire job before loosening the first bolt. Had to buy an extra set of LS3 heads to send out for port work. Sold my stock heads for the same money once the job was complete.

Do the headers first. You can run around just fine without a tune. If you do the other work first, you'll probably need a tune. Then you'd need to touchup the tune once you got the exhaust system completed. Better to do it all at once.

Probably some disappointment. If you can't get rid of whatever extra intake charge came in, power increase will be less than hoped for.

The full desl or really just making repairs as was said.
if I don’t put a new intake, headers go to a mellow or cam. I’ll probably hardly even notice a difference if at all.

I was told with that ghost cam I could experience vacuum issues in my car. I’m very ignorant with this sort of thing
I really wanna be excited about what I’m doing the fellow who is putting the motor together who has a shop and is experienced told me this.
Any thoughts? Is that even a possibility what he saying. Cause I love the recipe ghost cam fast intake, strong, lifters, long tube headers. I’m just gonna need it to be really stock like user-friendly no matter what I do. I apologize for going on, but I’m only gonna do this one time and all your guises input is super helpful to me.

It would take a much bigger cam to induce vacuum issues. You'll be fine.

What would be considered a large cam?
Medium cam.?
stock cam? For my LS two I know I have so many questions but the truth is I really do wanna make enhancements fast intake long tube headers all the rest of his stuff. It’s gonna set me back quite a bit of money. I just don’t wanna be disappointed with the street manners. Probably cost me six grand-ish. All in
help. lol I wish I could be satisfied with bare minimum, but I cannot and I don’t even know a happy medium

Small: under -4*'s of overlap
Medium: under 8*'s of overlap but over -4
large: over 8*'s of overlap but less than ~

Moon position in relation to Mars may skew things up or down. If you believe less is more or more is less, you're absolutely right.

Absolutely you can go smaller than what I suggested. At some point, it's not worth the time and $'s to do a cam swap.

That sounds so right.
If I follow the recipe along with finding a competent tuner can I be sure of no drive ability issues and a large grin behind the wheel???. Man you sound like you been doing this for 30 years.

I don’t race the car, but I drive the car and I drive the car fast from time to time. I’m probably looking for whatever everybody else is looking for longevity with performance. It’s kind of looking guitar player, searching for tone at a low
volume.

I can tell you that I would like it, and I don't tolerate any drivability issues. I mean none. Tuner is the key. Any yeah, I've been hot rodding Chevy small blocks, big blocks, and LS engines for 45+ years.

Im 60. I cant have driveabilirty issues. None. But i really do want to drive the car and not hesitate to drive it any where

so this ghost cam would not be considered too aggressive for my 2000 c6 LS 2?

Dyno tune would probably be required regardless of the cam i choose?

I realize if i choose to do intake and exhaust later it require an extra trip to tuner at his price. But if I didn’t do at this time. Would the cam and thinner gaske wake up th car considerably?

I really appreciate you taking the time to help me understand what my options are
