I have a st220, and im wondering witch route to take at the moment.
Car allready is 260bhp, msds headers, filter remapped etc.
Its not possible to cam the 220 heads cos of the design and this finger roller type bucket thing!
So i have some jaguer heads and was going to see wat i can do with them, But im told to put aggresive cams in, i need new shims, piper quoted me £1200. Just 4 the Kit, witch i think it to expensive.

Then i though of maybe using the 2.5 heads, but dnt really no if it will be worth while, I no turboing is mutch easier etc, but dnt wanna go that route.

Anyone no mutch about this shimming thing!
need to get clued lol.

Thank 4 any advice Given!
