Bent Valves!
Wondering if any sr20 wizards could help me out? My car isn't starting, took it to a specialist garage to where it has been before and they found the compression was very low. On further inspection almost all the valves were bent! It used to cough and splutter on full throttle when it was hot...- Packham

Bang and all was quiet
:( Well thats blown it, I was racing yesterday when the pipe to the boost controler came off so max boost and no fuel cut. Melted 2 plugs and munched some valves just in the middle of getting the head off to see the damage and start saving. Oh the joy of motor sport- freebird

blow off valves?
i've been looking into blow off valves and was after something that will do the job but not sound too over the top (i want the atmospheric vent sound, but quite subtle). i was considering getting the bailey evo piston type valve from apex, as i find the ssqv fitted to my mates sti way too loud...- DeanS15

We are going to do some final polishing, but this is the head after CNC machining for bigger valves and a full porting job. Interested of your comments :)
