Stock head gasket limit

Recommended Posts

I have now sourced a nice replacement engine for my supra but will be giving it a refresh before fitting it.

 

I will be changing the bottom end bearing and fitting ARP, Main, Big end and head studs together with a new oil pump.

 

I am currently considering if I just refit a standard Toyota head Gasket or I go for a good aftermarket one.

 

Note I dont want to fit a cheap metal cometic ect as I have seen many problems with them not sealing properly on other engines.

 

I would either use a HKS or cosworth, but I am not sure if even need an uprated one as I was suprised to see the standard gasket is a steel multilayor type.

 

I will hopefully be running just over 600 bhp when it is all back together.

 

So the choice, replacement Toyota gasket, or good aftermarket gasket?

 

Let me know your thoughts?
