Rock auto has both,
The HS set at 143.89
The HST set at 169.79


NAPA shows
The HS set at 234.00
The HST set at 209.00


Head Bolt set is FPG ES72892 runs about 40 bucks.

Torque Sequence per SB 02-06-01-003B
Issued April 2008

5 O 3 O 2 O 8 O

7 O 1 O 4 O 6 O

Start at 44 lb. ft.
Then 95 degrees additional.


Intake replacement:

Service Bulletin 03-06-01-010C
Issued April 2008

dO bO aO cO

cO aO bO dO

a/b get initial torque of 62 lb. in. then
c/d get initial torque of 62 lb. in.
NEXT
a/b get final torque of 115 lb. in. then
c/d get final torque of 18 lb. ft.

May develop an oil leak if you don't torque the verticals first.
Recommended that intake bolts be replaced as well.

Yea all new FelPro bolts the better gasket set "HST 9957 PT-1" is on
the way from my bud. that own's the garage $170.00, the head bolts 30
bucks, intake bolts 29 bucks Autozone, they knew of the better head
set but did not complain on the refund could not order from there
warehouse. I must confess I work in the IT field but if one gasket set
is improved or superseded by a better one is the deficiency of the
latter one worthy of a valid sale ?

Still no reply from FelPro I would like this pdf download they are
supposed to have for free download on the NEW torque spec's, also in
the past I always do a 2nd pass re-torque over night for "newly
installed part settling" especially on head repairs were just the
heads were resurfaced, need a good cleaning method for the block
mating surface the Acetone based cleaners wont clean all the old
stains from mating surface, thinking about some fine grade emery
cloth, what say you guys.

The OEM head gaskets used a different material for the gaskets. The
updated ones use a stainless inner layer to keep them from shifting.

The OEM Intake gaskets use a modified nylon material as the substrate
for the silicone sealing rings.

The problem with this is the way the gaskets on the newer engines are
held in place.
Older engines sandwiched the gaskets and had direct clamping with bolts
at a 90 degree angle. Then makers got this brilliant idea on how to
reduce assembly time of the engines by angling the bolts. The problem
with that is that now the gaskets are compressed in shear. Add in the
constant heat, expansion/contraction and lower tensile strength of the
plastic and you get failed gaskets.

After-market places saw the problems and developed gaskets that cured
it. BUT it took the OEM's a while to repair the problem.
Also while you hear all the time about how bad they are when it comes to
repairing these issues, keep in mind that for most companies if they
make 1 million engines and only hear of 500 failures they consider that
acceptable. Especially if the failures come after 60-70K.
For instance I have owned about 15 4.3 engines. According to what you
read they are terrible engines that all have bad intake gaskets. I have
replaced a total of 3 sets and all of those were after 100K.

No need to re-torque the new gaskets. They are compressed properly the
first time and have to have some give in order for the parts to move
once in use. HOWEVER if you are putting the engine together and it is
not in a heated garage then you may want to check the numbers after
running the engine the first time.

Don't use abrasives if you want the bearings to last. Clean off the old
crud with a scraper or a bristle disc (NOT A SCOTCH-BRITE type DISC).
Then wipe it down with some cleaner and button it up.

Great reply Steve it's always so refreshing to get a response so
seasoned and informative and highly experienced as you obviously are,
thank you sir.

Still no reply from FelPro on my inquiries, Steve my engine is a 6
cylinder engine 3.1L, my bud just droped off the HST 9957 PT-1 head
set he said the guy at the engine shop said this set also has an
beefed-up head gasket as well.
