The V8 Owners Forum -

Im pleased to say thanks to Caprisport, i went and picked up a pair of big valve stg 2 heads that we have done a deal on ,
So AT LAST i have a decent pair of heads ,



Inlet= 41.47mm Exhaust=35.57mm










This means i can now go ahead with getting the crower 50233 cam orderd along with the Rhoads or Crane hi-rev lifters, and try and make this piston cutter,
I'm hoping to have every thing together and running the week upto Easter (bloody hope so as got a show on easter monday)

Bout time as well bet your a happy bunny today.

yeah mate,
im over the moon,
and the valves are larger than normal,
the guides are bulleted and shortened, and have been machines for the later style neoprene stem seals,
looking at the chambers we think they are 28cc, identical to a 4.6 we had there, if that is the case the heads have been faced off so will defo need the pistons doing now.

Marki this is a shot of the springs mate you wanted,





I'm going to be one happy bunny if these are stg3 heads marki

oh forgot to say, the last visit to V8DEL the heads had a few valve springs renewed also something to do with not correct ratings as with the others,

just mailed V8Dev,
as on there site they say they catalogue there heads,
and under the lifting eye is another stamp, which reads, V8D21
fingers crossed they still have these heads listed and they can tell us exactly what was done etc.

My present heads on my 3.9 are stage 2 from v8 dev's and straight away from the piccies i can see that my exhaust ports are bigger than yours yet the valves are a standard efi valves.

Mine are "ported to gasket size, bulletted guides, later stem seals, latest efi valves, matched chambers uprated spriings"

Any pair of heads from anywhere, even if they are the same "stage" are never the same it seems!

Hopefully Gav V8 D can shed some light onto them,

well could not leave the heads alone,
had to start cleaning the chambers up ready for CC'ing

Both heads now cleaned,
needs a trip to parents dish washer in the morning now





your going to get me shot marki

don't blame me lol

Well,
Father was there today so could not sweet talk mum into letting me use the dishwasher,

So it was good old elbow grease today



and pic of the inlet






I CC'd the chambers and they came out around 30-31cc
but not sure how acurate my syringe is and if some of the water didnt go in

so at a guess i think these are 28CC chambers

what would the comp ratio be with tin gaskets??? (9.35:1 pistons)
it's around 9.35-9.40 with comp gaskets and 28cc chambers is it not?

Wanna nice ally sump to go with your new heads??
