[johnny2300]

Earlier last week I posted a ropic regaurding heads here and after pulling the head off it came off in two pieces and this here is the first for me to see a head just crack into two pieces like that even with head being made of alum thats got me blown away looking at the head being cracked like that it blows me away and now I goto find anew head and I was just curious if I can get twin cam for my 1.6 or not or org was sohc 16 valve and if I could what are the advantages of running a twin cam head to a sohc head??<P>Thanks John
