I have a Grubee GT5A which High Compression Head can I use? I think the GT5A uses a Super Rat head. Does anyone know where I can get a high compression head for the GT5A?

I wonder why the Pirate or MM heads cannot be used? If it is only the difference between 6MM studs vs 8MM, you would think the holes in the head can be filled and drilled, or maybe a spacer to run 6MM studs?

Or does it have to do with a difference in the piston dome shape?

:)

if I wanted to boost my compression a bit I would buy a couple sheets of abrasive paper and begin lapping the head. AL is soft and reasonably ez to take down a mm or so.

Start with some coarse paper, rotate suitably as you progress, and you should get noticeable results.

An expansion chamber will get you the biggest results.
