Best cost (cheapest) AFR 190 heads
It seems that my stock 89 L98 ported alum heads are the restricting points in my car. How much money will I have to spend to get a set of AFR 190 heads? How much will these heads flow up to, if thoroughly ported?
Thanks

Black,
I just got a set and they ran me about 1800 after everything was done to them. Watch the lift cam you are using the stock springs on the afr's are only good till .550" That is plenty for most cars but with the 219 cam and 1.6 RR you will be over that. I'm not sure if your running that high of a lift cam. But just watch. And make sure you get all the sensor holes drilled. They will cost you ~50 bucks. And lastly you may want to have them milled to achieve the correct CC. They will advise you better than I on this matter. You can follow my progress on "The Project" post. Good luck and you can see the Air Flow numbers at http://www.airflowresearch.com
good luck and if I can help just get ahold of me.

If you buy from an AFR dealer the price for L-98 AFR190 should be around $1200.00 plus tax or freight or both. If you have dual cooling fans you will need a second boss drilled in one of the heads for the second cooling sensor.
Like "ski_down_it" was saying, lift will determine if you need to upgrade the valve springs, and your desired C/R will determine if the heads need to be plained down. The AFRs come in 68 cc or 74 cc. I got mine from Dick Allen at the site below. When they came in they did not have the second sensor boss drilled so he got it done for me no charge. I did not want the heads plained since I wanted to maintain a 9.1 to 1 C/R for a blower. I also did not need any additional springs since I am using 1.52 Pro Magnum lifters and a blower cam and the LPE 219 will not exceed the max lift with the 1.52" lifters. My price was $1195 plus tax. I also needed angled plug heads so my 1 3/4" hooker long tube headers fit properly.

Good Luck with your decision.

Does anyone have dyno results pre and post heads addition (AFR 190 or similar)?
*****EDIT*****
I do have a set of ported cast heads with the 2.02/1.60 valves in them with a 3 angle valve job. When the engine was torn down to the block, my mechanic suggested I use my vette heads, and we ported them. The valves are the stock 1.94/1.57 (I think those #'s are correct) in them. Is it the valve sizes that's limiting me? Should I remove the alum. L98 heads and throw the cast ones on?
