I bought all the parts to my car except the heads, so I sent AFR a email for their recommendation. I was planning on using the AFR-195 for my street engine but here is what they had to say:
Dear David,
The 210cc heads will be the best choice for your combination.The heads will be fully cnc and will flow 285cfm intake and 220cfm exhaust.The heads will have a spring that will handle a solid roller good to .670 lift. The heads will come in a 76cc or 66cc chambers.The heads will start at $1450 complete ready to bolt on. and $739 for a bear as cast head with just seats and guides only. these heads are not finished and will require alot of work. We are about 6-8 wks for delivery.Thank you for your interest in our cylinder heads.Please feel free to call with any questions that you may have.818-890-0616.
Sincerely,
Marc
