I wouldn't do it, and let me tell you my story, LOL.
I ordered the F1 formula valve body with the service kit (both filter and filter screw) also ordered the maghytec deep pan.
I placed my order on NOV. 9!!!!
They told me there was a 4 week build time on the valve body.
I had no problem with that. 2 months go by, and I call them, and they said they would get it to me soon.
Another month goes by, and I call them and finally get my valve body shipped to me, just the valve body.
After reading the problems, people had with this company, I was skeptical even to put this valve body in, so I checked the torque specs on the valve body, and they weren't even torqued properly. Hence, I pull the valve body apart to check and make sure I got what I paid for $.
The check bal and everything else looked proper, so now I'm still waiting on my deep pad and my service kit.
I have called almost every week for the past 4 weeks, and all they say is they will ship it soon, and they will call me back the next day to confirm and let me tell you they have never called back.
It's always me who has to call complete scam, and never will I buy anything from them again.
I still have to call today and try to get a refund.
I read that if you ask for a refund, they will ship your order the next day and what a load of $hit.
I wish I knew what I know now.
I would use Revmax or Suncoast.
