How fast have you been with a AFR 225 N2O only.
Considering Ronnie is an Engine builder I would guess he did. However I do know that he used to use a guy by the name of Oscar down in Miami to do a lot of port work for him. You could always call and ask. Call Mustang Specialties in Fort Lauderdale and ask for Ronnie.That head is better than i thought. How did they get such a bad rap? 5.00 is getting with it for stock valve placement!! I don't give a shit who's box they came out of! I would like to know who worked on them does anyone know?
My heads are TFS R heads not high ports. And yes i am working on a combo for X275. Whats your opinion on the R head?But the weight added is minimal at most, it is not extreme. You have the ability to make a lot more power with the high ports. I also think you are putting to much emphasis in the head for the ET, the perfect cam for the cylinder head plays a major role. You can have 2 completely identical motors and just have a different cam, and it changes the whole combination. Keep in mind that the guys putting up eye popping numbers with these heads have had the same combo's for 5+ years. That is a massive amount of data and knowledge to gain not only on the motor but the chassis of the car as well. All of these guys have 1.20 and better short times on a small tire. Also your ET's are only going to progress as your race program progresses.
IMHO the 235 is a much better head and based on previous posts from you, I assume your looking to run X275 with this particular combination. Which means you are not penalized based on either head you decide to use for this combination, so I would choose the head with the higher performance potential.
I will be contacting him. ThanksThe heads come from AFR CNC'd. He bought the same heads that are available to ANYONE......Ronnie did NO additional work to them.....His number is 954-942-5202 extension 2# at Mustang Specialties, in case anyone needs to verify!!!!!!
