I'm looking for some feedback on Pacemaker PH4000 headers - are they any good, what they fit (body-wise & cylinder head wise), and any other useful comments good & bad

late reply? e series 302 windsor with E7 heads

these are the tri-y headers arent they? i have a pair on my ef v8 let me give you a tip its easier to install them from underneath the car and feed em up and also you should get allen bolts because i bought the smaller bolts for them but i had so much problems putting the bolts in because of the bends in the pipe my v8 only has the e7 heads but its made a diffrence to the note and its given it a bit more pickup on the lower rpm and revs out easier.

I'm pretty sure the EB Xr8 I'm working on atm has PH4000's on it, it sure as hell has GT40P heads. Man the plug angles are tight, so close to the pipes, with 90degree boot angles at the plug end I don't seem to have any issues with the plug leads hitting the extractors. Only just tho!

Cheers
