In the precious post, the last flow number on the exhaust is with a pipe
All intakes numbers are with a clay radius, the exhaust is without a pipe except the last number

I always wondered if the 304 head would be best of the iron heads
because you can open up the intake and shape the short side radius. |

Boris,
I like the 304 heads because even if they had a valve job or two the holes are small enough that bigger valves are no problem. The runners are basically the same as the bigger valve heads. 232jav3sp, Should be on the dyno in a month. Going in a Hornet wagon 304 bored to 3.8" with custom forged flat top pistons, 10.5cr, Molnar rods, Bullet cam, either a performer or torker intake, |

You sure got those little valves moving some air. Should be a fun, little engine. What's your target rpm?

Very happy with the air these heads are moving
Decision was made to run an Air Gap intake which will work well on this engine,
The car is for my customers wife so he wanted a good driver which is why the cam is on the smaller side of things. With this cam, I think the engine will peak at 5800-6K. |
