15psi and head lift =

2Tone93GT · April 27th, 2009, 12:19 AM

Blew a head gasket Saturday on the dyno. Guess 15psi and stock head bolts don't play well together. Anyway, here are the pics.

Heck yeah. ANYTHING will be better than these stock piles.

superbean · April 27th, 2009, 10:34 AM

time for metal hg and arp studs. No more lift!

flattusmaximus78 · April 27th, 2009, 10:51 AM

Whats your set up. And upper and lower pulley combo?

flyin ryan · April 27th, 2009, 10:54 AM

15 psi LOL yeah stock heads/gaskets and bolts aren't gonna hold long... you could get by with studs. That's what I use with stock heads/gaskets i figure with the stock gaskets they'll let go instead of something more costly.

flattusmaximus78 · April 27th, 2009, 10:59 AM

I have arp head studs and head gaskets from the fms gasket rebuild kit. I'm going I had a 3.33 pulley on my vtech, but I'm stepping down to 3.00 but I'm not looking for 15psi thats for sure.

MustangMatt96GT · April 27th, 2009, 11:00 AM

Yeah he is putting in some arp bolts. But I like the idea of putting in a weaker gasket so it blows first... Might have to look into that.

flattusmaximus78 · April 27th, 2009, 11:03 AM

bolts ftl... go with studs.

MustangMatt96GT · April 27th, 2009, 11:07 AM

I meant to put studs... My bad

2Tone93GT · April 27th, 2009, 11:19 AM

I'm running the Vortech provided S-Trim one piece lower and a 2.75" upper.

Rest of my stuff includes:

Trick Flow - Track Heat
Unequal length shorties
X-Pipe with Flows and dumps
75mm TB and spacer
75mm MAF
UPR's version of the power pipe (forgot what it is called)
255lph in-tank and TRex
Professional Products fuel rail and regulator kit. (worst fitment EVER! FYI)
MSD digital 6
Blaster coil
93 Cobra rockers (Crane)
Hardened pushrods

...think that is it.

2Tone93GT · April 27th, 2009, 11:24 AM

I'm going with ARP studs for sure. I have a friend with some ported and polished GT40s that need a guide and a valve I'm trying to get him to sell me. Eff putting those stock heads back on when I already have them off.

Considering these:
SCE ICS Titan Copper Self Sealing Head Gaskets - summitracing.com
or
Domestic Auto

Opinions on either of these guys?

I'm glad you like. That gasket will be hung on the garage wall for sure!

89LX347 · April 27th, 2009, 12:43 PM

what did you make?

409 right before it blew. There was still quite a bit of fuel we hadn't got to waiting to be added.

Beautiful car too btw man. I LOVE black notches!

ryans88gt · April 27th, 2009, 01:44 PM

go with fel-pro 9333pt1 gaskets.

They are a great gasket for boosted apps and are cheap

To go with metal gaskets, you will need the block and head surface remachined to a much smoother finish.

With a good tune you won't need to worry about that. A weak gasket is a weak gasket. It could cause other problems. An engine spinning 7000 rpm with a couple cylinders full of coolant is not a good thing.
