Depends where you are. On the Central Coast I recently had my heads done on my VK 304 so it could run strait PULP If you pull the heads off yourself it will cost about $600 to $700 plus what ever the cost is to replace the carby for the gas unit.

Dion,

Ken is correct here. The mod they do to the heads is the same mod for running PULP or GAS. If you go to the attached page you can see the specs for a gas head yourself.

Dion & Craig,

Stage 3 heads are OK with a modified donk. If Dion's 308 is standard with standard pistons he will have the same problem as you, a major rebuild. There may be piston to valve clearance issues. A Stage 3 isnt what he needs as I read it. H
