I have some Dart 225 heads and some 241 casting heads. The 225s I was going to run on my 408 that I had built for my Camaro. I am not above using those heads and getting something else for it or using the 241s. They are on a LS1 I have that I am going ot be putting in my Suzuki Samurai so I am not above using them because I will want it to make everything really low in the rpms since I am building it for off roading. I really don't want to drop 2+k on a set of heads for the Camaro because I think the turbo will mask a mediocure head on it.

 

L92 seems to be a good set up but I think you have to do a slight over bore. Not 100% sure though.... I think you can get it done with 317 though especially with The Tbss intake and 90mm throtlle body. Milling wouldn't hurt it I just think the 243 would put you around 11.1 and I think that would be a little much... esspecial if you plan to tow...

The right way to do it is to assemble everything and see were the piston is sitting with the deck to calculate the real compression ratio...
