um, the 7a ones work fine with 25psi boost and on 4age and 7ag atmo race engines and they are $70 trade.
If you dont know anything about gaskets or engines get a TRD one If you have even a tiny bit of skill or knowledge and dont want to waste extra money on a Trd gasket when a 7a one does exactly the same job.
From memory the TRD gaskets are $120 so you save $50{which is nearlly a set of Rod bearings}
But people should make there own choices, i just know what works from experiance.
