how much do you gain with 202s over 188S?
Sometimes you can have too much velocity. Think of what happens filling a water bucket up with a garden hose pointed too close to the bottom.
I put MP 360 heads on my low compression 318. With the 2.02 intakes. Heads were milled just .030 and I used .040 thick head gaskets. Sounds like a bad decision, huh? Motor seemed to make more power everywhere, low-mid and high rpms. No I did not try the 1.88 intake valves first.
