Who does the best LT1 head work????
Port size plays a ton in a motors ability to produce power, both on small and larger cube motors. Go too big on a small motor, you lose port velocity and your numbers will suffer. Go too small on a bigger motor and you'll choke off it's ability to breathe, and your numbers will suffer.

Ever hear the saying "the proof is in the pudding"? They are now offering a 200cc package as well. That motor is about 1.7hp per cube at the crank and that is with heads "too small" and intake that according to most here are not up to the task of a strong street engine, that is still MAF even
.Far as a answer to your question I think you are better off with a good 195cc port than you are a poor 220cc port.

I really need to get some locals to vouch for how NOT a racer my car is, not that it is anywhere near the level you are talking about but I just get tired of everytime a combo works people want to believe it is all in the car, often it is in the car more than the motor but we still need to give credit where it is due and recognize a lot of shops are doing amazing things with stock castings these days, things just a couple years ago were "impossible".
also a buddy of mine with a 180cc h/c package from AI with stock exhaust manifold is claiming he ran high 11's
what do yall think???

I just wish the LTx castings were the way to go for my setup.. If someone honestly told me a LTx casting will get the job done and meet my goal's, probably would hvae saved the 1800 that i spent on bare casting's and umteen other $$$ porting, and what not.. All's i'm trying to get at.. every car requires' a diff combo.. And the same head that work's great on your 350 might not get the job done on a 383 or larger cube motor... It might make Ok power.. But there is def. power left on the table.. Even in the 350c.i sector...

My car doesn't dyno well, but it puts up the numbers where it really counts...

Thanks for all the great input. I guess the biggest question I am asking is how big of a diffrence can a cnc port job make...can a 195cc runner cnc port job make the flow numbers a non cnc 220cc port job make. fbodymotorsports claim these heads will make more power than most lt1 heads with port sizes up to 220cc. Has anybody ever bought heads from these guys?? As I said I will also be running a solid roller camshaft probably in the 240-244 degree at .50 duration...not huge but not small...this will be a street rod...not a drag strip caror rather should I say it might see the drag strip, but it will mostly be a street car...thanks MM
