Really John, that's just trolling there. That engine was hydraulic locked or the head bolts weren't torqued properly. Thumper- they are Chinese heads.... I bought the Eddie heads- the Stealths weren't on the market yet- and would recommend them, just because they are made in the USA. The Eddie heads are known to need setup work, no different than ANY aftermarket head- some of the MP stuff needs Major work. I'm having Brian @ IMM do a full setup and porting appropriate to my build. He's given me a very reasonable price and I like supporting a local shop.
