ZachBreck Posted July 23, 2007 Report Posted July 23, 2007 I am looking at getting cool head for my 05 LE. I have pro flow with K&N, FMF pipes and boost. Do I need any other mods or just throw them on. Do I have to mod anything or what exactly do I have to do. Thanks for the help Quote
shee rips Posted July 23, 2007 Report Posted July 23, 2007 assuming you dont want to go crazy with the compression, you dont need to do anything else other than bolt it on there Quote
Slickgib Posted July 23, 2007 Report Posted July 23, 2007 throw it on ...and see what happens.banshee baby Quote
shee4speed Posted July 23, 2007 Report Posted July 23, 2007 I'm wondering what the performance gains would be by adding about 30-40 psi.compression. Quote
Hilarious Posted July 23, 2007 Report Posted July 23, 2007 I'm wondering what the performance gains would be by adding about 30-40 psi.compression. More power. More lower end torque. Quote
ZachBreck Posted July 23, 2007 Author Report Posted July 23, 2007 Is there any mods that come with adding 60 more compression? Just 17 domes and I should be ok? Quote

jbooker82 Posted July 23, 2007 Report Posted July 23, 2007 If you get a noss head you dont have to change out to longer head studs. Plus you can get them anodized and 10% discount for BHQ members. Quote
ClimbAnyHill Posted July 23, 2007 Report Posted July 23, 2007 I think they go for $225 from NOSS or FAST. Comes with choice of domes and Oring kit. I'm sure you know to dump the coolant out before attacking the installation. Used light amounts of grease to seat those rings & make sure cylinder surface is clear from debris. You can put the spark plugs on the domes and drop them in along with the bottom plate. [Makes guidance easy.] Remove the plugs and drop the top piece in and start torquing in 5lbs increments.. Go 5,10,15,20. Follow the stud pattern as shown on the stock head! Quote

quickbansheeman Posted July 24, 2007 Report Posted July 24, 2007 does a cool head really make a difference in power? Quote
ClimbAnyHill Posted July 26, 2007 Report Posted July 26, 2007 does a cool head really make a difference in power? Yes it does, increases compression in your combustion chamber. Smaller domes, more compression! Quote
