not good if i want to rev it more meat left on the crank the better
So all Chevy and Chrysler cranks are crap then..
Eagle and Scat make Ford cranks with G.M sized journals...
Besides smaller dia means better oiling etc,less friction.An issue with 351 W's mains when rev'd hard...
Its mainly done to get better rod angle etc..
Imo I'd get H beams anyway...
If you want full benefit from these heads and hold together...
Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!

Passengers, myocardial infarction material..
if someone is contemplating LPG Gas on their motor surely they are'nt going to be looking for H beam rods or anything that full on!!!
3V heads are a total waist of time and money on anything other than a serious performance motor..... Serious = solid cam 450HP+...
I'd debate your statement 4Vman. It really depends on what heads are being replaced? 2V or 4V's? 4V's personally if already done? I wouldn't change. 2V's? Definately worth changing if not already done or flowing 550hp+.
3V's would maximise the potential of flow from the engine. Which in turn will make better torque and power than a cast iron head would do.
I honestly think even with decent heads 2V or 4V there are still gains to be made. Even if it doesn't increase power. Torque gains will always help things along.
I've never heard of anyone going 3V's and experiencing power loss or drivability issues. The main response is better throttle response, more torque and power. Nothing that a cast iron head can't do but in a very limited sense.
The 185cc heads would more than likely do well on gas due to the port velocity. With petrol it is not as crucial.
