NOBODY WANTS TO REPLACE A HEAD GASKET - THE INFO BELOW WILL HELP YOU STAY ON THE ROAD


ABOUT HEAD GASKETS:
Our Best Brand head gaskets do not require "sealant" if the decks are flat, near-new,  fresh, unscored and clean. Sealant is built into the gasket.
Name goes to up to sky. Start Torque at 25 pounds, using the sketch above, in numerical sequence and increase incrementally 5 pounds at a time to a final torque of 55 pounds.

ALWAYS re-torque to 55 FOOT POUNDS  a minimum of three (3) times COLD. . . . NO Shortcuts.
Run the engine with plain water to its normal running temperature and allow to cool before re-torquing.
By the 2nd tightening, seepage, in most cases, should be gone.
After the 3rd cooling and retorque you should be ready to push the engine and have fun.
Drain and fill with your choice of coolant.

Attention - Warning:  After years of research concerning gasketing and sealing of Model "A" and "B"cylinder heads it is now considered fact that over torquing head bolts or nuts will: 
Warp the cylinder bores.
Pull up metal around stud holes.
Lesson the integrity of the block's stud threads.
Effectively break the gasket seal. 
Most heads are not as strong as the block so additional warpage of the head/block is to be expected if over torqued. 
(Many old-timers may disagree but they usually are quite good at replacing head gaskets.)

Conventional wisdom  and years of experience has shown 55 foot pounds to be the sweet spot for Model A and B engines, whether they are stock, high compression or overhead valve machines. Adding more torque warps the engine block enough that water seepage and blown head gaskets start to become the norm.

What type of gasket material is best to use?
There are several types of head gaskets available.
There are 3 types that show consistent failure in engines with compression ratios over 6:1.
1)  Copper sandwiched over composite;
2)  Silicone impregnated composite - gray comp and grey comp with red silicone.
3)  Solid gray and black composite.
I do not have engineering data to interpret the constant failure of these 3 type of gaskets.
All I know is,  from hundreds of reported of failures,  that these types have a problem. 
I sell and manage the sale of thousands of flathead and overhead cylinder heads. Without a dependable long term strong head gasket my products would be worthless. My cylinder heads have several special characteristics that improve gasketing.
Namely: overkill strength and super fine flat ground surfaces. My heads are actually stronger than the block.

I only recommend Best (brand) composite over steel head gaskets sold on this page used without sealant. Signed, Charlie Yapp.

BEST GASKET COMPANY: makes our very special cylinder head gaskets like this:
GraphTite™ consists of a Kevlar reinforced graphite facing material is mechanically bonded to both sides of a perforated steel core.  This modern engineered, high-performance material is rated to a temperature of 1400 degrees-F.  Steel fire rings are installed around the combustion chamber areas of the gasket. 
 
GraphTite™ head gaskets have superb sealing characteristics, excellent torque retention, and hold up to the punishment dished out by high-performance engines – high quality all the way.  This gasket might be overkill for cruiser engines, but so what . .  extra reliability never hurts!
 
Install GraphTite™ head gaskets; There are two trains of thought. The preference of Scalded Dog Speed Parts is to NOT use any sealant coatings if your head and block deck are new - fresh - and flat. If your assembly is iffy then use a spray-on sealant like K & W Copper Coat or Permatex Copper Spray-A-Gasket.  Always re-torque, no shortcuts. Always re-torque to 55# when engine is cold, three (3) times before hard driving.  NO shortcuts.​

The number one "thing" that blows a head gasket is a combination of high engine torque and too much heat.
This is the situation found when attempting to run the engine up hill in third gear . . . When you know, in your heart, that it needed to be down shifted.  . . . . Boom!  It also can happen in drag racing and hill climbs with sudden powerful starts.

If you plan on pushing your engine (and want to get home) . . . get a back up. . . . Our special gasket box can hold up to three (3) head gaskets. Shipping in the USA is $18.50 (subject to change) whether it is 1, 2 or 3 gaskets. Buy a couple extras and save up to $33.00 in shipping and if you're a SOSS member save an additional 10% off your parts order.

Disclaimer: As much as we try to be helpful, we do not have any control as to how your engine is used or built.
We can not warrant head gaskets after being installed and used. These are good gaskets, installed and used properly should give excellent service.
