I have got an EFi CVH head that im thinking of getting Ported and possible bigger valves.

Can somebody recommend somewhere to get this done and give me an idea on how much it would cost?

I would also like advice on if its worth doing on my spec.

Cossie Managed
Wossner Pistons
PEC Rods
Newman PH4 Cam
Solid Lifters
Possibly going to run a T34


I have a ported MFi head but i think i would rather use the EFi one so i dont have to run an adapter, does anybody know if the newman cam and lifters from an MFi head will even work with an EFi one?



cheers!

Give NMS a call they've done a good few powerful cvh lumps.

I have a phase 4 newmans in my efi head and when I bought it I don't remembering stipulating mfi or efi so I'd say yes.

yeah cams are interchangeable, nms did a trick head for karlos G's old cvh, he was pleased with it.

Didn't something fail on that though? Or do I have that wrong?

studabear

something happened, can't quite remember what though, he had it repaired,

NMS do fantastic cylinder head work, I would have your head taken to there stage 3 level, which is good for 280 bhp on the right engine. Might be worth looking into your con rods before going T34 .

NMS or you can try Neil Roper http://www.roperdevelopments.co.uk/

Norris Motorsport..The best around in my opinion, little pricey but you get what you pay for, never had any problems with my engine they built. Give them a ring, you'll get a 30min phone call if you speak to karl as he could talk for days about anything! interesting to listen to though if you dont already know it.

Price wise, i cant remember how much my head work was as it was done with the rest of the engine.

Sitech Racing - simon smail & Nik beswick, they did a cylinderhead for my high spec zvh build, my mates who do a lot of porting and have a few of the top spec tuner heads on the shelf stated it was a goodun which was enough for me. I think they have a few heads already done, I was running the newmans phase 4 cam i think which was developed for the zvh but Im pretty sure they are the best make of cam out there for the cvh, had a few others in the past, piper and kent, both of which ate them selves.

Norris heads are very expensive but I think there has been a lot of development gone into them and they are one of the few gen. tuners producing big bhp cvh's which actually stick together in one piece.

Hope this helps mate

Thanks for the replies it seems NMS are a popular choice lol I will get in contact with him see what the crack is.



What's wrong with PEC rods on a T34 is that above their limit?

I'll give Neil roper a try aswell thanks

this is good to hear thanks.
