Is it possible to find out by the engine number what the block is? I am asking because whenever I change the head gasket I notice that I have 3 indents on the piston for valves. I think the dash head is 3 valves ~ so I am thinking that it is either a Dash block or Dash pistons in it?
The head I am running at the moment has 2 valves per cylinder only. The spare head has double valve springs with a Crow cam but also 2 valves per cylinder.
Any assistance for this would be greatly appreciated.

8 valve pistons have 3 valve reliefs in the piston as the exhaust valves have different positions between cylinder 1 & 3 and cylinder 2 & 4, it saves having to make two different sets of pistons.

Out of interest are you running 30 psi through stock pistons?

No, I am running no balance shafts and a bit bigger pistons with 3 indents but a standard head and cam at the moment. I have to find a new clutch and pressure plate to suit my driving. Also I need to get a new Crow Cam because on mine one of the lopes has about 4 mm missing from wear, my guess would be that the valve got stuck and wore it.
I put a picture in photobucket of the engine so you can have a look what it looks like bolted in. You can see a few mods.
Other then that, yes I am running 30 pounds of boost and loving it. Ohh, and I have a varex muffler as well and when I open it under boost it feels like I have another 30 pound turbo kicking in. :D

30 psi!, what turbo and other mods do you have?

and what's it making on the dyno? :D

Thank you RiceThief.

I have to chuck some rings into it one day and I am trying to work out what rings I would have to buy. The engine is out of Starion_kid696 Ja Starion. I bought it of him.

I run a MPI with 4 x 1000cc injectors and a Motec computer. A Garrett T4 BB Turbo and 3" exhaust all the way. Turbonetics delta gate mark 11 with front mounted intercooler. Forged pistons.

Sorry no dynos. Whenever we tried the dyno they blow the headgasket ~ that's why I am that good at changing the head gasket because I blew 7 in the last 6 month.

I should point out that I am not a mechanic or a spray painter or anything at all to do with cars, I just wing it, lol.
I just give things a go and see what happens. Too many people just take it to the mechanic or get it painted by a pro. I need to paint my car and will do it in the shed here. Never done it before but why not give it a go. I am the ONE that has to like it.

I think blowing 7 gaskets in 6 months is a good sign not to run 30psi..

Running 30psi could lead to more detonation and therefore will actually net you less power than a lower boost level. I wouldn't think the SOHC 8V head would keep up too well with the flow either.

If I were you I would be using a cometic multi layer steel head gasket with ARP head stud hardware. Sounds like the head is lifting up at high boost.

I don't think it is so much the 30 pounds of boost that is causing the trouble with the head gasket ~ it is more like when I open the muffler and it is like a second turbo kicking in. At the moment I drive with the muffler closed also I have a couple normal head gaskets in the shed for when I do blow it.
multi layer head gasket and arp studs are in the future to go on but I have to get a new cam first as well as a clutch.
