Do you have flow numbers for them or any dynos???

The car was a rocket, but I dont know if he ever actually got a good power pull down before selling it... :(

We also did some substantial porting to the blower housing that seemed very effective.

That would be my car now

well numbers man! dont keep us in suspense

Haven't dyno'ed the car just use it for a daily driver (dyno will come soon)

I know I want one for my skittles car.I have a new FR head in box I need to sell 1st.

Massive spends alot of time and money on the kits and parts they sell thats why its taking so long on there turbo kit.Yeah some some people might have gotten proto types but thats what they are.Karl has always stood behind his work and parts,Massive has been working on these heads
for long time and now there ready

kdog... if we already have a cylinder head, are we able to send it to you and have to port and polish it, clean it up, install new valves and springs/retainers?

Wow...two thumbs up, if I had a third you'd get that one also. Love the flow comparison...can't wait to see the Duratec comparison. Now if we could get an outstanding company like Massive to manufacture an intake manifold that doesn't cost way too much, and actually bolts on without having to relocate steering components.....man, the dollar signs are rolling... keep up the outstanding work!

You can definitely go .045". Some have even gone as for as .080 (Focus Central back in the day). I would say with all but stock cams you will have an interference motor.

FR head is based on the same stock casting as ours, so you could certainly mill it the same and have no issues.

Im 100% sure that the work was effective amd produced more power, but I dont think we ever flowed them back to back. The last one we did was in 05. Based on the response I have had to people wanting an SVT head, I'd say its more than likely we will begin working on a program.

We could. But you understand there is a $300 core charge already. So we will need your old head as it is. It would save you down time versus having to wait for that particular head to be done versus just having us send you one right away. We have been including a pre-paid UPS label with the heads so returning it is a snap.
