You dont even need headers to get the exhaust out, just use the head gaskets

I really think I'm going to put the D1 back on the car for a while, no reason to hurt something this early in the year. It would be nice to get the car in the 8s but I really dont have the engine hardware to keep trying

DarkblueTA

Damn man. I don't blame you on putting the D1 back on. Are you using head stud?

Of course, even the D1 would start doing the same thing after around 70 passes or so but not quite as bad. I'll save the F1A for something a little bigger I think. I'm trying to keep this as low maintenace as I can, head gaskets after 70 passes I can live with, these have 35 that I counted and never pushed any water until the last couple passes and look worst then the last time.

O-ring the heads and run 6.0 GM MLS gaskets. You'll thank me later.

But first, make sure your not detonating.

Also tq bolts to 80ftlbs with oil.

I was thinking of that. You would only O ring the heads? Or the heads and block? I'll only be running 16-17 lbs. Should I even do it to my motor??

Hmmm..I did mine to 100... yikes

Why do you think that's happening with a safe AFR and no det? Just too much cylinder pressure at 20psi for the head studs?

I wonder why ?!

I run the 6L MLS @ 80ft lbs with moly and ARP 12pt studs. Its the newer block with the short studs also.

I'm not really seeing any detonation, looking through the last two logs the a/f never really got over 11.8 or so (both the BS3 wideband and the LC1 in the other bank), timing was as 15 degrees @ 6200, 14 degrees @ 7000.

I guess it could be detonating some but I dont see any signs anywhere, piston tops look great, that funky grey color is from the fuel I'm running (112 sunoco leaded). I'm not a huge fan of O-ringing steel gaskets, never really worked in my old nitrous BBCs.

But I have a feeling I have a lot more low - midrange cylinder pressure with the higher compression and smallish cam then a lot of guys, plus the higher IAT isnt helping. Like I said before I never really intended to put 20psi into this engine. I did it to use with a maxed out D1SC and it seems to work pretty well.

As far as those other fancy gaskets from what I have read and seen they just dont work any better then the MLS gaskets if everything is right.

I think I'll just wait until the newer blocks hit the market and run this one with the D1 until the end of the year, if its a choice between runing 9.20s-9.30s all year and running 8.99 and making a few passes I'll take the mid-low 9s.

im in the same boat right now. still making the decision whether to get the cometic fusions or not. hmmmmmm

I would just try the MLS gaskets first.

Most people will never have these problems, I make a lot of passes and I'm pushing this thing pretty hard every time its run. I ran the car 24 times last year, when I play with stuff I can make 10-12 passes a day. Thats more then a lot of guys will run in 5 years so I its amazing that things hold up as well as they do really.

had gm mls gaskets. i realize they get the job done on many high hp cars, but im just trying to take more preventative measures so i dont have to refresh every year. as it is im putting new bearings and rings in the thing.

my only cice is that i was on bolts, and not studs, but that is definitely changing. not sure if thats going to be enough though. my wallet cant support my hobby

and i want to get a nice apartment and do other things in my life than cars....lol

If ya run and race the car enough your going to need to change gaskets no matter what bran ya run..................

Have a couple kids and a big house, few other hobbies and then tell me about it Not like its real hard swapping head gaskets but I'm waliking the line between 'fun' race car and pain in the *** race car right now lol.

Besides Kyle should get in the 8s first since he has a green car, we all know black cars are the fastest so I'll watch him try in the spring
