i'm wondering what kind of head work do people with high hp do. i am in the process of building my car and im just wondering what people usually build up on their cylinder head. I know stock heads can make a lot of power and etc. Dohc Vtec heads only plz.

Don't bump. SEARCH !!!! You aren't the first to modify an engine on this forum.

i've know people running pretty much stock heads , just upgraded valvetrain maybe a mild port and polish.....u can make up to 700 on that with the right setup

 

You really don't need headwork to make serious power with a good turbo setup.

But that doesn't mean you won't benefit from it. I know that my cars setup is really efficient due to the fact that my head has been reworked. If my head were stock I wouldn't be making the power I am making.

hes the loser b/c your *** is too lazy to search? ya good call their chief

 

i did search but couldnt find much useful information on high hp apps.

 

"high hp" what do you call high hp man?

 

500hp and above

 

Square head by milling the deck parallel to the camshaft bores.
Mill chamber reliefs around each valve seat.
Custom radius/discrete valve job. Larger than stock seats at no additional charge. Seat heights set to within .001" intake and exhaust to insure the same piston to valve clearance in each cylinder.
Rework port bowls and blend into seat asymmetric seat radii.
Blend and smooth chamber.
Match intake entries and exhaust port exits Mill head to CC specification.
Full chamber rework.
Full intake port rework.
Full exhaust port rework.

those are a few of the things I know of that some people are running making over 500whp.

To me that just alot of wasted money when u can easly make over 500 with a stock head.. now if it were on an all-motor setup the i'd say hell yea.....

 

yeah that's head work for cars making well over 600whp He wanted to know what kinda head work for hp cars...haha

 

yeah i wanted to know what kind of head work people are doing for FI, i know people are making good power with stock heads and i know i could spend money on other stuff but it doesnt answer the question.

 

my buddie was making 510 on a stock head,, i know someone making over 600 on a stock type-r head ....... my buddie is gonna be making close to 700 this year with a stock head with just full valvetrain
