This auction is for a "lot" of parts that would be needed to swap out your current Datsun Z car head for the higher compression E-31 casting Head found on early 240z models. Boost your compression and your Horsies!! Included are: 1. One (bare-bones) E-31 Head high compression alluminum head in great shape. (some VERY mild porting done) Cam towers are included, but you should probably use your old ones if you are not also installing a new cam. I also have most of the valve train parts if you don't want to use your old ones . or need extras. 2. One brand new set of Exhaust Valves for this head 3. One complete set of Piston compression ings. (for 2.4l standard bore) (why not replace while you've got the head off?) 4. One complete Fel-pro top-end gasket set. Including head, valve cover and every other gasket/seal you will need to complete this job. 5. One complete engine front-cover gasket/ seal set. 6. Misc hardware etc for the mounting the new head. This is a complete package that should be real handy in replacing your e-88 or other cylinder head with a highjer performance option. This should boost stock compression ratio significantly. EM me with your zip for a shipping quote. Probably around 30 bucks.
