I have a pair of LS1 heads that are ported with 2.05/1.60 valves, very nice work but I do not know who ported them. They are stamped "I.H.S." on the end. Does anybody know who would stamp there work like this? Any help is appreciated.

Thanks, Ryan

 

I hate School

IHS


i have no idea thats a first

 

Post this on Ls1.com or LS1tech.com's engine boards there are quite a few people there with ported heads and they may be able to help you find the anonymous head porter.

 

Thanks for the help, I will try LS1.com. I hate school too, its funny though how I went to college & then was a school teacher for 3 years.

 

There is a place called "INTERNET RACERS SUPPLY". I think they used to have ported Ls1 heads. They used to be ferred to as "IRS". Maybe the IHS is actually IRS?????? Go here:
