Spend the money on your heads,
Not worth the postage let alone the sale price!!
C.O.M.E. are doing good heads atm for a good price.

I ahve a good mate with a reputable dyno workshop that has had plenty of customers turn up with those Boat Anchors, Firstly, every port flows up to 20% different to its neighbour, secondly, after you spend another $1000+ getting them ported properly, they Crack...Nice waste of hard earned cash.....

If you just won Tattslotto, go for it, coz you have money to burn, otherwise steer well clear...IMO........

Oh yeh and your manifold wont fit... hmmm seems like the manifold is warped....
No the heads are about as precision as a leggo Block,...
Sorry, but just what Ive heard from someone I trust!!

Scrap is not worth anything near what they are asking. I would never describe them as cheap. The rest of your post is pretty spot on though

thanks guys, so basically, spend the $1500 (they did seem to cheap to be any good) on my factory steel heads and i would end up with a better set up, or save a bit more and go for COME or Yella Terra?

$1500 on your existing heads woul get you a nice port job and a vlave re seat, go that way, much better reliability, and just as much if not more power :-)

there was a good add on ebay telln people how good those heads are! nothing wrong with factory heads well worth spending a few bucks on!

The greatest thing you could have done is asked for advice on this, which you have.
Nothing worse than hearing from the poor Bast@rd that spends his 6 mnths savings and excitedly tells us, just for us to rain on his parade.....

Before you buy anything like that, it's always good to get as many opinions as possible.

If you want your heads given the once over, talk to this man :-)

Heres 2 examples NOT to get procomp stuff.

That is absolute gold. I remember seeing one about gaskets as well. eBay generally ends up removing this type of stuff, or it'll get deleted when it gets old, so I am going to quote it here for any future searches about procomp.

I have for sale some very low km's 355 stroker parts, less than 2000 ks. These parts have been replaced over several removal and tear downs of my motor.

Brought as a PROCOMP 355 stroker kit and head, manifold, cam kit from Sydney Speed supplies also known as ## racing #####

First up is a wonderfull set of valve springs that went soft within 400 ks, next is a set of 7/16 screw in studs 1 is sheared off 2 are bent other than that they are in perfect condition.

I also have a set of big end and main bearings that I never used as the brand new crank needed grinding, It had a 1thou taper and was also barrelled from over polishing, This kit was ordered balanced for the cost of $250 extra and was so out of balance it shook the car severly at 2800 rpm, I thought the needles on my dash were going to shake off.

Up next is a set of pistons and rings, these items have about 1200 ks on them, the rings failed to seat and created a nice smoke haze behind me, they would suit a buyer looking for a unique look to there car SMOKE. 1 piston has a small crack, nothing to worry about as it is barely visible, the teflon coating (or as I call it paint) is worn off, this happened in 2 hours while running in the cam and tunning. These pistons have had 27 thou taken off them as they stuck out of a non decked block that far, they have also had the gudgeon holes honed to alinge them as the pin was very tight in these full floating pistons.

Next is a cam shaft, I was sold it as a solid but its either ground wrong or a hydraulic it is very noisy at the 22 thou clearence as on the cam card, A copy of a camtech cam with a camtech box and cam card. On talking to camtech they DONOT and will not have any thing to do with procomp. This badly made cam also damaged my valves where the collets seat so I also have these up for sale sizes are 2.02 inlet 1.6 exhaust.

OK this was the final straw that made me write this, I was putting the head back together after getting them back from the machine shop, seats cut and new valves, I put the valve stem seals on and realised I had to put the spring seat washers on before them. so i had to remove the seals. I PULLED UP ON THE SEAL TO REMOVE IT AND PULLED THE TOP CEAN OFF THE VALVE GUIDE NOT ONCE BUT TWICE. Im not quite sure whats going on there, either I have super human strenght or these items are super weak, Ill let you be the judge. So I am also selling these there seems to be at least 10 good ones.

By buying my items that are already USED you can save yourself the heart ache of buying off sydney speed/ PROCOMP and you will know you are buying PRELOVED and TESTED products, Yhis should ease your fear of new parts breaking.

I also have other item from the kit that are just as useless as the rest please contact me if you are interested in any thing. LOL AS IF.

The buy now is a rough estimate of what I have spent to fix every thing so far, its getting close to the $4000 I payed for the kit in the first place, I could have brought a C.O.M.E 355 stroker and head kit for that. And they may have cared if I had a problem.

These Items have been relisted as some one we all know had a whinge and got it removed.
