Ok, several cracks in my heads and really poor castings and pitting. Who here can recommend a good set of heads for a 2180 VW ? I know Empi is well known for street heads and there are so many variations put there Im a bit confused as to exactly what heads to buy. P.s. I think I'm going to buy an elison TB unless somebody has a better idea thats convincing.
