I have an order from AFR but they are 12-14 weeks back ordered on any LT1/LT4 head..

So I don't know what should I do.. This is a very very long time.. I sold my engine and I already miss my car..

Are there any head same quality with AFR heads???

I will go with 210cc ..

any suggestion will be great..!

Who did you call for your AFR's? Have you tried any other vendors like AI? As was mentioned above Lloyd does great work and that's not only on stock castings as he'll do port work on aftermarket castings as well.

If you're set on aftermarket castings, you may want to just order a bare set and have Lloyd or another porter do the work for you.

Honestly I think some hogged out stock LT1 or LT4 castings would work well with your setup. Also what chamber size is your 11:1 based on? I'm assuming that you're still going to want to keep a higher CR since you have a nitrous setup....right?

 

Paul from Thunder call AFR.. (Thunderracing is teh place where I order this list)..
Combustion chamber is 64cc as I wrote above.. Yes I will use nitrous for that reason I keep CR higher.. I want ~550bhp.. I will search on Lloyd Elliot ,but webpage is uncorrect I think.. I couldn't find their website..

If it were me I'd go with Lloyd for the heads and contact Bret Bauer for a custom cam....both of those guys are some knowledgeable ****'s and have put out some killer combo's separately and together.
