TH3P1RATE

Hi everyone, I bought a 99 m6 z28 from my dealership a few months ago and have been ironing out the kinks,doing some minor mods(strano springs w/ koni sports, magnaflow cat back) and reading up on a ton of info. So now it's time for more power and I'm looking for some input on my build list to see if there's anything I could improve upon.
GOAL: Nice weather cruiser with some autox and drag passes thrown in. I'm hoping to run low 12s/high 11s at the track not super concerned with max effort dyno numbers.

Cam-WS6 Store high lift ASA

HEADS:-junkyard 799s with pac1219s
-CHE trunion upgrade
-WS6Store .45 headgaskets

Exhaust:Speed Engineering 1 7/8 long tubes with ORY

Intake/ FUEL: slp lid
Dorman LS2 that i'll clean up the ports on
Warr 92mm t/b
GTP injectors

And of course there's all the odds and ends like hardware,gaskets and wear parts i'll replace while its apart. Thanks for the input!

What are your expectations for driveability?
Clutch choice?

TH3P1RATE

Driveability wise I know it's probably going to surge a bit at lower rpms but that's nothing i haven't dealt with before this isn't my first performance car just my first LS1 lol.

And I forgot to mention for the clutch i'm thinking of going with a monster stage 2 and the tick hydraulic upgrades

Reasonable expectations. There are other cams if you wanted something that was more daily driver friendly but if your expectations are realistic like you say it'll be fine.

I think you have yourself a solid street combo that will def run the times you are looking for

Dont use the ws6 store gaskets. Had 4 sets fail already. 1 under boost, 3 on just N/A motors . Not sure what's up with them, the company has been good every time they have failed and offered to replace them . But pulling heads in an fbody isnt exactly fun .

Do you know if the standard rebuild kit that comes with MLS gaskets are their own brand or standard GM MLS?

TH3P1RATE

What brand would you recommend I use instead, Cometic or OEM? I was hoping to go for a little thinner of a gasket to improve my quench but if it's gonna be too sketch i'll get gm ones, i'm not a fan of doing things twice if i can help it.

Should be 11's no problem. I did low 12's with far less.

TH3P1RATE

Thanks for all the input so far guys! Any recommendations for headgaskets if i should stay away from ws6store ones? and do i need to upgrade the rest of the fuel system or can it handle the power level i'll be at?

Wow, I thought I was the only one...., Ive had 2 fail but thought it was my fault.

Anyone comment on if the MLS gaskets are the same as @WS6store.com gaskets?

I really liked the idea of using the WS6store gaskets. Oh well, go with GM MLS and mill the heads for the quench and compression

I CAN NOT BELIEVE the WS6Store tech guy hasn’t chimed in here...

I don't like that ASA cam specs. That's a lot of overlap for a medium to low performance cam.

I think the Cam Motion Titan 4 227/232 .621/.600 113+4 or the Summit Racing Stage 2 226/238 .600/.600 113+3 would be better choices...

ASA is 11 degrees of overlap. Titan 4 is 3.5 and Summit Stage 2 is 6 degrees. I wouldn't want more than 6 degrees in a cruiser, tbh.

And if you end up with a little more compression, I think somehting like a 230/236 .621/.604 112+2 would be a better performing cam (though that's 9 degrees of overlap--but will pull higher).

Medium to low performance? Maybe the gm one.
We had one recently made 475 rwhp in an l92 swap with a 3200 stall on 6l80 and 20s.
Thats not bad imo
My friends wife dailys her 98 trans am and 2800ish stall and LOVES it with our high lift asa cam and she is super picky. he likes to race 5.0s and hemis when she isnt around also. Its a ton of fun and a great spec, so we can agree to disagree there i guess.

As far as the gaskets go, mavn told me he had one leaking, and i offered to replace or maybe even upgrade i forget but he said he would copper coat them no big deal...i have repeatedly warned against this and so do head gasket manufacturers. That coating is there for a reason. He said it was good and thats the last i knew. A leak isnt a failure but it is an issue of course. As to any more failures, he never told me personally and i didnt get any emails or dms over it either.
So far ddnspider is going just fine on his with boost even and we have a customer in Canada with a 370 thats 13:1 on pump and e85 and and 250-300 shot ran the whole season and finally torched on basically his last run because he went from pump to e85 and didnt tune correctly.

Every head gasket can have issues. It can be more than just the head gaskets fault if it fails though and adding copper coat can only cause more issue especially on a gasket that is fully coated like ours.
Sometimes the gm 8544 gaskets go on a huge backorder and our blue notched ones are all we have.
I have also used them on every one of my personal builds for a few 5.3s and iron 5.7s including the ones in my taking forver but its still going engine test. 0 issues so far.
If we dont know about it we cant fix it and just blurting something out with 0 backstory or notifying the vendor first doesnt help either.

I think you guys coming out with the High Lift versions of the Hot Cam and ASA cam made them into the cam they are supposed to be.
They needed LIFT, and lots more of it. Besides the better quality grind than came along for the ride.....

I’m still not 100% sure what my problem is with my 6.0 witch is why I haven’t emailed you about them yet, I have a set of the blue headgasket ones on 2 5.3 running around somewhere for one for about 6 months and another for over a year with 0 issues.

Well ****.

The only reason I didnt have my 862 heads welded up when they were back at TEA was because WS6store started selling the notched head gaskets.

Son's of a bitches.

Since i didnt know about the excessive amount of failures and just one he told me he fixed, we could not report this to the gasket company at the time.
Since then i did let them know and we have gotten ours swapped out with a newer revision.
This is why its important to let us know, whether you want them swapped or not.

Also i have personally built 2 engines since then that are running with 0 issue and we have sold at least 20 sets with no callbacks.
