What kinda numbers with AFR 205's and FM13? Current numbers are 368 RWHP on a mustang dyno with a half *** tune. What does my current number convert to on a dynojet? 380? 390? 400?
I have all of the mods in my sig, and I would like to slap on a set of AFR 205 heads (66cc chambers). What kind of numbers would I be putting down at the rear wheels after the install? I plan on getting a mail order tune from Jeff Creech or possibly a dyno tune from a reputible shop after the install.

Depending on your tune and bolt-ons, the AFR 205s should give you a solid 30-40 rwhp gain along with better streetability. The amount you mill the heads and thickness of gasket used will skew your numbers higher or lower. I recommend a .030" mill and a .045" Cometic gasket.

So are you suggesting a mill them after I get them? or would AFR do this for me? When I mill them .030 and use a .045 gasket, what will that leave my CR?
When I did the cam swap we hand sanded the TB out and hit it with some polish...its not necessarily ported though to the best standards. I should probably get one done by one of the well-known porters around here to get it epoxied and such.

I'm only milling .012 (66 to 64cc) and using a .040 Cometic - With the piston .005 to .007 above the deck, I'll be right at 11:1CR. You'll need to know how far above the deck surface your piston is to figure out CR.

I dont know how far the stock piston is above the deck...why do I need to mill them? Won't they be correct from AFR? or are you suggesting milling them for my application?

My 346/A4 makes 453 rwhp, but with a locked converter and bunch of other measures that only Allan Futral could tell you about.

If you mill them .030", you will pick up another half point in compression which will make more torque (5-10 tq increase). I suggest milling them this amount.

I dont plan on FI or nitrous...I want to keep it all motor...so I should be able to keep the compression up there. You will just have to keep the timing retarded and the fuel octane high and detonation wont occur.

I would probably do the +2 or none if I was running nitrous. If you call and talk to Alan @ Futral he will give you a better idea...he advised me to get the +4 when I talked to him back in May when I got the cam.

What is the piston to deck measurement on a stock internal LS1? Also, what is the compressed thickness of stock GM head gaskets? .052"? And where can I get the correct thickness gasket?
