any up for sell out there?

I have one set of HAM prepared 2.0 heads for sale with 42X36 valves, new seats and the full HAM treatment with 12mm plugs and etc.. I'll take 1,200 for the pair

This is typically what labor is for rebuilding 2.0 heads, but these have all new valves, seats, guides, springs and retainers (all our updated parts). These would be great for up to a 2056cc engine with the 96mm bore size.

i've heard when you go that big the cylendar walls are thin causing heating issues? is this different with quality aftermarket/o.e.m.? at what point do i need to machine case/heads?

96mm is not big, we consider the 96mm cylinder a stock replacement- I haven't buil;t a 94mm bored engine for 7 years!

A properly configured engine will not have heat issues, we use the 96mm cylinder at power levels to date of over 212HP with the stock cooling system.

Its all in the combo.

just wanted to thank you all who's experianced input has helped shape this build. it's a long road but so far we have located/bought most items needed for a 2056. i was a mechanic and built engines for years before my accident so this has been great learning walking kenny thru it.

i just need to get the (9550?) cam and a few misc. from jake 8/1/07 when the cams will be avalible. special thanks to sir andy for the bottom end items needed to make the 2056 happen. (IMG:style_emoticons/default/beerchug.gif)

along with locating parts we've checked previously balanced rods w/ bearings and nuts (29 oz.'s each) plastic gauged new rod bearings and built rod/crank assembly, sand blasted/painted tin, tore down spare 1.7 for parts/hardware misc. and located a set of o.e.m. swivel feet. we'll have them machined next week. this list may help give others an idea of whats needed to convert to 2056 from 1.7/1.8.
