what is meant by PYR port & polishing?
what did he do??

thanx

 

PYR is a shop in Houston. He just had them port and polish the head.

 

are they (pyr) any good?

 

I've never used them, but I've never heard anything bad about them. I've heard of a few people that had work done by them but never talked to anyone directly. They are probably the first one I will check out when I need some headwork done on my current project, but that will be awhile because my money tree is bare. Check out thier website http://www.pyr-racing.com/ Also talk to SwiftTypeR on this board, he knows the seller.

 

Tony the Tiger had his cylinder head ported to Toda Spec B specs by PYR Racing.

i'm sure the Toda Spec B cams make great power but to be able to move the speedo this fast the head needs to flow really well: http://www3.sympatico.ca/h.leung/Video/223ITRgear.mpg
