What size domes?


Recommended Posts

you could get it now or later.....when you get it ported though your builder will recommend either a shaved head or a cool head with smaller domes to up your compression levels.......if you ahve a cool head at that point they will let you know what size dome you should get and you can buy them directly from them. They are around $65 if i remember correctly.

Would it b better to go w 21's or b safe w 22's like he said

 

I did not say I disagreed with you that 22 would be safe. I was just stating what I had done and had no problems.

 

I got my info from noss machine website. Noted that they are approximates but "21's" should be ok. Not saying they will be though.
