go for a decent brand of gaskets and save yourself a fortune,
get victor reinz gasket set, they do a bottom end set and a head set will come with everything you need, and are top qaulity imo as good as the toyota ones and half the price,
i've not heard of having any problems and i sell them for a living, sold a few to starlet owners and have always fitted them to my engines, mini mondeo various starlet etc
or just go toyota
If you decide you want a Toyota head gasket, let me know, ive got one brand new sitting in my room & ill do it half the price Toyota want
