D24tic cyl head porting

[DWL_Puavo]

I just handled an -94 N/A casting head last summer because our old one (-84, N/A) was quite a bit broken. New casting was very nice, much better intake and exhaust ports than in older casting. No casting scrubs or poor casting quality. Also match porting the intake and exhaust was pointless because they were aligned just right. Our engine is in VW LT so there was LT's intake and exhaust manifolds.
