HEAD GASKET 1300 BLACK BK450 ORIGINAL GASKET

BK450 Standard composite reinforced gasket used on all large bore engines and is an exceptionally good gasket.

Asbestos free Compressed volume is 4.00cc.

This original Metro and Turbo head gasket has now been superseded/replaced by the GUG702560HG which has a different black rubber type "O" ring fitted on the rocker supply gallery.

Many customers prefer TAM1521 Payen gasket without the rubber seal which has been proven over time to be superior to even the copper version for competition, even though these new black type have been known to act as a thermal barrier between head and block which can tend to increase engine temperature, hence why people are still using good copper gaskets.
