I want to know who makes adapter plates for the L92 Heads so that I can put on the 1.9L magnacharger that I had on the old stock heads.

L92 heads require 4" bore your block cant even be bored that far. the most youll make is a stock 350 bore which is a 3.905"

look into a set of prc 2.5 243s

You can buy the correct lower intake manifold from magnacharger, its about $700

Do NOT use L92's..lots of shrouding.. The prc ls6 heads in a 64cc would lower your compression a little to the 5.3's 61cc and flow great with that 1900!

-SOO..
-346 ci = 3.898"
-350 ci = 3.905"

Or did you mean "The most you'll make is a bored over LS1 which is 3.905" I guess I could look it up..too lazy right now

yeah he cant use the l92's. the valves are so big, he will need a 4" or bigger bore. I would go with high velocity over a set of hulled out heads.
