Pricing? What can the spring pockets be opened up to?

 

I think we need an AFR 205 vs TFS 205 sponsor shootout!

 

is the price the same as the 215 I would imagine?

 

Hope not cause they dont flow as much as the PRC heads for 1/2 the price.....?

 

I think he is talking about the TF 215's.

 

For the chromoly retainer heads $1995.95. Ti retainer heads are $2195.95.

The spring pockets are 1.480" and can be opened up to handle a 1.550" spring but you can not go deeper on the pockets.

 

But for the Price I would just go a different route IMO

 

Perhaps may I suggest that you make a small writeup on where and when do you recommend those heads (application, cam range, rpm, complementing mods etc..)
Why them over the 215s, why them over stock casting ?etc....

 

I agree, Im curious to know too.

 

OK my cam runs 595"-598" lift that falls below the 600" max but is quite close. Is this safe or would I need upgraded springs?

 

X2! Thanks

 

velocity. There is more to a head then flow numbers.

205cc head vs a 220cc head.


those numbers are close to the same with the AFR 205cc heads.

 

subscribing looking forward to a write up

 

I think I want these!

 

What is the differance between 205cc and 220cc so I know for the future. So, I understand better. thanks

 

+1 id like to know how theyd work out with my torquer 2 vs the maybe the 215cc

 

bigger port. bigger port flows more air which = higher cfm/flow numbers

you lose velocity though. so unless you have the cubic inches or forced induction to push that much air through a bigger port, your going to give up low end power.
