What lake?

HB, just buy a 16 classic and pizz on that baja. You would look good in a classic:D

Inconel valves are not always necessary on naturally aspirated marine engines. I have been running high compression big and small blocks using Manley Severe Duty Stainless valves for years and have never had a problem. As a matter of fact the Stainless valves actually flow a little better than the inconel valves. Blower and Turbo motors are another story. Especially very high HP versions of these definately require inconel. Again, only my opinion.:cool:

Better yet, Are new valves even Necessary??

AND-- Exhaust valves?? I thought when the piston went down, it exposed the exhaust port? Guess 2 strokes are farther away than I though....

Manley "severe duty" valves are stainless.
Manley "extreme duty" valves are inconel.

2-strokes don't have any valves near the piston. Some have rotary or reed valves upstream near the carb, but nothing in the cylinder except ports for intake and exhaust.

4-strokes have intake and exhaust valves.

As far as exhaust below waterline, my old Correct Craft sounded cool like that...

HB- go here: 4 strokes

to learn about 4 strokes.

Hyper,
I'm sure that ZZ4 would work fine. However, make sure it has stainless or marine head gaskets if you're running raw water cooling! Also need to think about a marine distributor, alternator and starter. Automotive stuff won't do here.

Can you post up a link of where to find those parts?

Anyone know where to find cheap headers?
