I was wondering if there is a reliability difference between the cut stock head and a billet high compression head? And what compression ratio you guys are running if using the high compression billet head or the stock head with the dome inserts. Thanks

spend $20 and cut 10,000's off your stock head. Why spend the $300. You don't even get the bling factor w/ the lay down engines cause you cant see the head.

$20.00 dollars is a geat way, but the billeet heads have changable domes for different compression, and if you wreck one you don't have to buy a whole new head, and the biggest plus they add more coolant witch helps alot on keeping the temps down.................Johnny

Well if thats worth $300 then do it. For the 2 extra oz. of coolant it wasn't worth it to me.

Firecats need all the cooling help they can get, thats what drove me to get a billet head.

It is not justthe extra coolant, but how it is around the dome more the hottest part. F7 run at pretty much the max for temp that is the reason for the billet heads.............Johnny

also, don't most domes actually have different shape chambers ? Yes, you can have the stock head cut to increase compression and have the chambers modded for better burn. Best answer is do what is within your budget......

Well did u even try the snow flap extension?? They scrape the ground cus there so low.
