my engine is stock bore.....i dont think i need anything too special for a head gakset, ide rather a composite gasket then a copper,a lot of high psi dsm guys are going back to the facory part,
on that note, my buddy greg(who built me wide band and Ms)
is building stroked out 46g3 2.3 with over 30 psi boost, he ran 12.1 last year smoking all 4 tires at 27 psi, i cant wait for a run in that car
