This is a hybrid of our Cylinder Head Preparation and Cylinder Head Selection articles. A late-May call from a dirt short track racer in upstate New York prompted it. He has two sets of cast iron cylinder heads, a “good” set and a “bad” set. The “good” heads are small block Chevy, prepared by the very capable Randy Brzezinski. With them, his car is a front-runner. But, like any racer, he wants a little more from his engine and called Total Flow Products to see what we could offer. Our free inspection program and cylinder head selection process are ideal for this type of call. |

A racer once called and asked us to improve the brand “A” heads he had just installed. He believed there was additional potential in the new heads, even though they already made more power than his old brand “B” heads. Experience told us his “B” heads were actually a better design for his application and had even more potential than the “A” pieces. When the racer mentioned his “A” heads had been prepared by a reputable engine builder, and the “B” heads by an amateur, the whole picture came into focus. |

There are two objectives of cylinder head maintenance. The first is to maintain peak performance by identifying and repairing normal wear. The second, and most important, is to preserve the head by detecting early signs of problems and preventing them from becoming destructive. |

There are two ways to determine whether or not cylinder heads require the additional sealing capability of wire O-rings. The first is simple – your application. If you are running high compression, forced induction (super charger or turbocharger), nitrous or high engine speeds, your heads may need O-rings. The second way is even simpler and it overrides the first - If your current application is working well without O-rings, don’t bother with them. Spend your money and our time on other parts or processes that will improve your engine’s performance. |

In the “Cylinder Head Selection Factors” issue of Tech Talk, we mentioned the media’s fascination with “racing” flow benches. Here’s why that type of “competition” is a poor method of predicting performance or selecting components. |
