Hi mat i was hoping you would see this . the block and head was fully reconed with new stem valve seals etc . but i am starting to think that it can be the only thing left as you say . i have another head but do not know its history . might be worth sticking it on just to see .
will get some pics up mat , looks nice stting in there and go's like stink . looks standard on the outside , even used the standard rear pipe to keep it looking bit of a sleeper ..
