Are Chevy 193 heads good?

Are Chevy 193 heads good?

The 193 heads are a very good head for trucks. I wouldn’t recommend them for an over 5000 rpm engine though. They have the ‘swirl ports’ – great for low end torque and mid range power.

Are Chevy 882 heads good?

882s could be called the best of the worst. The catch with performance engines is you can usually find ready to run, used aftermarket heads for $450-500. Granted, they’ll be small, like a performer or dart iron eagle 180, but still offer significant improvement over a stock head.

The 441 has a reputation as a good-flowing head among the production 76cc chamber heads. In this particular case, it lost out to the 882 head, but overall it’s a decent head that responds well to pocket port work and larger 2.02/1.94 valves….

How much horsepower do Vortec heads add?

Are 350 TBI heads any good?

Those are 350 “swirl port” TBI heads. The intake is severely restricted due to the old-tech swirl-port design that blocks off half the intake port because of the “swirl ramp”. The exhaust ports are acutally quite good for their day, not far from the flow of a later set of Vortecs, however.

Are these heads sub-5000 rpm?

They are definitely sub-5000 RPM heads. The lift is limited to about .450″ before the retainers hit the guide seals, so you’ll be OK in that respect. About the only thing you can do is measure them.

Are vortec heads a better deal than TBI’s?

At 4K rpm, the TBI’s were down 30% compared to a Vortec and the margin continued to grow. That’s when I decided buying $500 Vortecs was a better deal than spending $400 modifying the TBI heads. $200 in bowl blending, valve back-cut, v-guide reduction and a quickie de-burr and the Vortecs were posting some very decent #’s.
