re. Re: increase in valve size, turbos, and seats

Jim,

I'll be using a similar configuration in NG head on MC bottom end.

What turbo will you be using?  I don't know if my T03/T4 will get far into the 300 range - great bottom end though.

I'm still mulling over the MC-1 vs. MC-2 with respect to compression too, as I don't know how much issue I will have with detonation on the MC-2, and how hard it will be to tune it out, or whether it will be worth it.

Valve seats or car seats?

The most common mod is to have 40mm intake valves from
the NG motor put in.  My next head will be 40mm
intake, 35 mm inconel exhaust valves, ported, Ti
retainers, and a 272 cam.  You probably don't need all
this though, I'm gunning for 400 whp on a 10vt.
