what is the best head gasket?
I have a 4.5lr 1fzfe and it is running between 14psi and 20psi . depending what I am doing .
I have been using factory head gaskits in the past but every 2-3 years it lets go so now it is time to fix it properly so I am going to get arp head bolts for and whant to fit a better head gaskit with it.
so what can i use felpro /acl or are the toyota ones the best to use.
cheers

[quote="RN"]So do you support your local vendor...not if it is going to cost me almost double. [quote]
Toyota Head Gaskets are Prety good standard ones ,
But certainly Not the Best
ACL High performance are good ,If your driving up a Street and see a quilty Engine Builder stop and see him ,He'll beable to get a thicker one to extra Boost and stand up to more abuse,
Someone on here might Know someone in your area

[quote="bazzle"]What about a once off machine of the head to put an O ring groove in ext to the comb chamber. Use copper ring when assembling to seal.

I tryed a copper head gasket on my last engine and it didnt like being parked up for 3 months at a time between comps and the coolant would leek out from under it.
so it is time to give the cometic gasket a go if I can get one

If you liked the Brass Headgasket you could use Organic coolent it wont go Acidic

Its not necessarily a copper head gasket but copper is best with correct coolant and sealer.. Its a ring around comb chamber that gives a better seal.crazy eyes wrote:I tryed a copper head gasket on my last engine and it didnt like being parked up for 3 months at a time between comps and the coolant would leek out from under it.bazzle wrote:What about a once off machine of the head to put an O ring groove in ext to the comb chamber.

Why not O Ring the block.
Get a groove machined and tap in a hardened wire ring.
Used to do these on the little E15ET motors in the turbo ET / pulsar. I've put 18PSI into them stock and seen up to 38PSI going into them with different pistons / rods / crank.
