<VV> Re: HIGH TECH for street engine?

[Bryan Blackwell]

A clarification:

The "step" is the raised surface that the gasket sits on.  The filled 
in area of a '65 to '67 95 HP head is the "squish" area.  By milling 
one of these heads .050" inches and using a .032" gasket you will 
achieve a high turbulence "squish" area that will help reduce 
detonation.

My personal choice will be a 110 shortblock with 95 heads milled as 
above and adjusted to true 9 to 1 CR, mildly ported, with 140 exhaust 
logs into a crossover single exhaust built from 140 U pipes.  Should 
run on 89 octane in the Greenbrier with full advance.

BTW, for more info on heads, you might see my website:
