How to cut a HIGH COMPRESSION, HEMI HEAD for the YAMAHA BLASTER (revisited)

[JoeAK]

This is fun! Its not terribly hard to do, and the power output is well worth your efforts. No need to rejet!
A VERY noticeable power increase! When coupled with a ported cylinder with matched transfer ports at the case, a quality pipe, and proper jetting, You can expect 30+ HP INCREASE which is double what the stock output is, and still have the reliability.
These videos are 7+ years old. The lighting, camera, and microphone were antiques then and I suck at doing videos, so don't rip on the old man too hard. I hope this helps someone out.

So in your video your chamber is 16 cc that seems small. If I were to do this to my head should I keep it the same or take off less from the initial cut to make the chamber a bit larger.

Larger the chamber is more afm right.

I believe I said 19cc, but I have to go and check. Those videos are from 8 years ago.
