Thanks

afr 185's for sure...If I had to do it all over again.

I have TFS TW's and they are good but 185's are just a hair better I believe.

what about putting that money into your holley's ? $2000.00 into porting and polishing i wonder how they would flow ?


or are you going to sell the holley's ?

Keep your heads and PORT them man!!!!!!! All you need is a base head to work with for your application. I believe you would be very happy with some race porting on those Holley heads. My heads flow 340 cfm and they rock! Save your money and port them.

canfeilds and trick flow "r"s are great blower heads..i own AFR 185's for a NA aplication..had i gone blower i would of gotten trick flow "r"s

dss told me that with my heads the comp ratio would be 9.2:1 . Seems a tad high for 14 lbs to me. Flow really isnt that important, This is a street car and i believe it will be strong enough.I think they are 62cc heads. I need to check.

ok then they port the roof of the heads to raise the cc and lower compretion ratio if thats what you want. if there 62's then most of the other heads might even raise it above 9.2-1

Sounds good, im gonna check with my speed shop tomorrow about a good place for head work.
