    Some say long tubes.. Others run shorts.. I don't know about OBX headers.. I will tell you the gain difference between the 2 won't be substantial @ the same time any will be better than stock logs.. The intake side on the stock l36 cylinder heads is restrictive and little can be done to stock l36 heads for improved flow other than a blower or a spool or 2.. You could P&P them but there's nearly nothing to work with.. Water jackets are too close to the intake port walls..

    L67, heads are the same castings with the exception of bungs for the injectors in the heads.. Factory l36 heads have the spots cast in them but are not drilled.. I'd look into after market heads imho..

    In these photos is a new set of l36 heads I have in my shop.. If you look above the intake ports you can clearly see the l67 injector bung spots.. Also these are the ports small by any standards..



    Exhaust sides don't even match the exhaust manifolds inside diameter. Head (exhaust) openings are oval and the manifold ports are round and over lap the oval in spots..

    Google intense racing and have a look see.. They carry perf packages that include heads and so forth for starters.. Or try 3800 performance.. Just have to research on what's best for your goals..

    Good to know.. I sure hope the performance fuel pump I got from them for my other v6 project is worth a crap when fire up time comes..
