Much better as they MP heads will easily outflow a set of stock/ported
heads. You can go up to 1.97 on the intake and still not loose any
noticeable bottom-end.

Subject: Re: DML: Re: stock valve sizes?
Dont need tolerances but I do have a question tht will require an
opinion. I have the opportunity to buy a new set of aluminum MP magnum
heads with 1.92
intake and (I think)1.65 exhaust valves. The price is right (about $900
for
both heads complete with valves, springs, locks, retainers, seals) but I
was
wondering how much of a performance increase I might expect. It doesnt
seem
like the valve size is much bigger than stock.
If I'm not going to see any significant increase in output then I'll
probably
just get my iron heads ported to 2.02 (although they say I'll lose some
more
low end).
see below for my mods
