Hi guys
I'm looking at doing alittle headwork in the coming month to my Evo VII
I'm running a TD05HR 18G 10.5 single flapper tubro

So far i have
BC Single spring, titanium retainer
Kelford 272s
Tomei gears

Is there anything esle in the head i should be replacing while its open as my cars on around 110000ks I have already replaced Water pump and timing belts

I wasn't going to pull the head off and get it ported as i don't see much gain but is there anything esle worth doing

 

I'd say get a better set of valve springs...BC stuff doesn't get much love here. I'd suggest Ferrea or GSC's. Also a set of arp studs would be recommended.

Good Luck with it and have fun.

 

why not angle port the head there is plenty of benifit doing that?

 

This is is right on time because I just picked up a spare head and have kelford 272's to put in it an was wondering the same. Is Ferrea worth the money? What kind of gains would you expect from the port and polish or angle job?
