Sorry to hear about your luck!

Mike's correct need to figure out what changed to prevent future problems.

Too bad you didn't start a thread sooner we could have twisted your arm into upgrading to EQ heads, wouldn't have cost much more with the sale of yours

Not 100% though. I would say it's more likely the builder may have picked out a cam close to but not exact with tighter lsa, etc. I've seen that happen a lot with engine builders that predominately do street and track builds. Just not marine savvy.

Mike do you think the spec is different enough to have caused all my problems... What cam would you replace it with? Is 525 cam cool?, keep in mind I'm going dry exhaust
