gs is gooing in for a head gasket replacement.

[RACER-X]

where is the cheapest place i can order the upgraded gasket replacement? also since the block and head will be off; what should i have done at the machine shop as far as porting, and how much can be done?

 

[LaserBrndU]

get the head ported, polished and plained. get your manifolds ported and polished as well

Napa has good head gasket upgrade i believe

If you run a 420a (profile says 4g63, but your in the nt section) get the stock one from the dealer. Call Bob Kise at fourm and he will hook you up.

the stock one from the dealer is the same one napa sells but the one at the dealer is more $$
