exactly,,keep on posting,,the 2 of you.engines must sound killer

I would rater learn from other peoples mistake and prevent mine. Same goes for the others. LOL

I sold my boat last year, just ride with my brother now.

I made quit a few mistakes over the years and learned a little along the way.

One thing I learned 55mm and .937 lifters wont work rite without using a lifter bushing the axel goes into the oil galley and will leak out the bottom.

I've seen the same problem with standard cam and lifters it ends up gauling up the lifters.

My preference is to start out non cnc and have professionally hand ported and assembled taylored to specific application. If I'm going to spend the extra money I'd rather help support someone who not only knows what their doing but themselves also. Plus a good head porter will outflow any cnc head. My personal experience and opinion of course but the power to be had in heads is huge including SC application. I will find the link here on OSO which involved SC build with Merlin heads vs other cnc head if I recall. If I recall it was smitty not sure but regardless the gains where huge.

Post #7. Not a true comparison from same head non cnc'd vs cnc but thought I'd post anyway. Still shows the power of heads.

When I had my buddys dad port my AFR I picked up 20-30 cfm over cnc... I was told a good hand port will always be better flow over cnc
