I did some searches and didnt find alot of dyno numbers with there heads. I would like to buy there longblock 408 it is cheap for what it is. I also read a big thread about there heads flow numbers sheets are false. If you have one of there motors let me know your dyno numbers and your satisfaction. I am undecided on whos longblock to buy but they are the cheapest that I have seen so far. Thank you

 

Just cause you buy there long block doesnt mean you have to buy their heads. I purchased my 408 from them & waiting on the arrivial. But Im running Patriot heads. All FFHP built is the short block.

 

we are no longer doing cylinder heads due to the market but we offer many differnet brands of cylinder heads for the ls1. we did an LT1 for Nate@nastyPerformance with a set of our LT1 heads and it made just under 500 RWHP and right at 600 RWTQ on only 6 pounds of boost.
