I had some J heads that were very rusty in the waterways and they broke through even with 'mild' porting!
So I made some cutaways for myself in the style of 'WESLAKE' lol.
It was welded by a pro shop but it still went through again DOH!
The first pic shows a narrow area behind the valve stem so bee careful here...
The exhaust ports were plesently 'FAT' everywhere.:thumbsup:
