First where have you guys gotten your AFR heads and how much have you paid? I was looking at there site and I looked at the 190cc and the 195cc heads and Iwas wondering what was the difference since there flow numbers are the same?

Which head do you think would most suit my set-up?

A roller 406 cam 224/230 .55x .56x 112 LSA
Superram intake with 30 lbs. injectors
MAP set-up
forged pistons with a 125 shot of NO2
The pistons I have make a compression of 10.3 with a 70cc head so I will prolly go with the 68cc head and it boost it up to around 10.5-10.6.

thanks for any help

 

190 vs. 195: the only difference is the intake port opening size ... just means you have to use a different FelPro intake gasket ... 1204 vs 1205. The 195s are better suited for higher RPMs as long as you have the intake matched for that opening.

I would actually go with the 210s (not the 190 or 195s) for a 406ci engine.

Sounds good whats the going rate for the AFR's?

 

I bought mine through a GP at Z-racing http://www.users.qwest.net/~zjon/z-racing

Jon's sometimes slow with email because he's pretty busy, but he saved me about $100. I worked with AFR to figure out the details of what I wanted and then ordered them through Jon.
