This is my car. I'm very impressed with the results. The heads made a world of difference. And Mike tuned the car to run better than ever. Thanks again Ron and all the guys at Vengeance Racing!

Awesome job by everyone at Vengeance. I should add, awesmome job as usual. Damn Ron, its getting redundant with your posts. Everyone of them is a huge success for the shop and the customer. No wonder business is so good at Vengeance despite the recession the country is in. Vengeance is still motoring along............

Very nice numbers there. I may have to look into a set of those when I get ready for my h/c swap. To the driver, I bet that car is a blast.

For every 1 point in SCR, power increases about 3%.

Ron.... you should do a test that back to back tests them against some 243 castings, that should take out the compression difference and put them up against the best stock castings out there.

BTW why not put smoothing on 5?

and there's still a decent amount of room for improvement in those as cast castings.

I wonder what it would have been if the compression ratio was kept the same and that little spike at the end of the graph wasn't the "peak" HP.

Yeah that's why most people set SMOOTHING to 5.

PIB, I think there is if you were to smooth and hog out the Intake and exhaust runners. Still for the money its a great bang for the buck! Especially when they come assembled with the upgraded trickflow springs from Vengeance.

No need to hog anything out to improve them some. Any experienced porter can do what needs to be done in a day. Tough to get people to give up their secrets though But yeah, they're a good bang for the buck.

How would these heads do on a stock cam car?
any ideas?

I only ask because i am tempted to do a head only swap this summer using a budget head. Of course backed up by full bolts ons and a good tuner.

the other heads i have in mind are from TEA, TSP, or Patriot. Never thought i would see a budget trick flow.
