Used Afr Head

Is It Worth To Buy A Used 205 Cc Afr Head ? The Guy Is Asking $ 1700 & I Don't Know How Many Miles Are On Them Yet. Waiting For His Reply To That Questions. I Kow New One Goes For $2300. Also How Many Miles Is The Springs On The Afr Good For Before You Need To Replace Them ?

Also I Have Set Of Used Zo6 Heads, I Can Get Them Ported,milled, 5 Angle Valve Job, Hand Blend Them From Patriot Performance For $650.00. Should I Just Port My 243 Heads Or Is It Worh To Get The Afr Heads Instead ???

Personally I'd go with the z06 heads... I'm sure they flow very well and you can put the rest of the money elsewhere... cam?

I do have a mild cam. comp cam xr 275 hr -12 222/224 566/568.

If I port the 243 heads plus shipping cost & $500.00 spent on the 243 heads, I maybe better off with afr & sell me 243.

I'd grab the AFRs at 1700 if they were in good shape and ready to bolt on...
