helicoil in heads

Lots of info! Thanks for the tips, i'm sure that i'll have to put a helicoil in again sometime and the more info the better. It's also nice to learn some history about them and understand what i have.

Fishy68, i think thats a good idea, i'm glad you told me that. I could get better flowing heads for less money, and i wouldn't ruin the purity of the heads i got cause someone out there would like them stock.

Time to go put it back together.

Thanks,

Steve
