QUOTE 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. QUOTE 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. |
