My winter project is a head rebuild on mine which is a CF24358UF on it. I cant quite work out tho' the details of what head I have and maybe what to do when its at machine shop? Plan is full cleanup, new valve guides, cut for lead free otherwise its fix or upgrade whats best. I am tho always wanting more ooomph but am concerned on doing this without looking at the wider picture.
Any tips`much appreciated but somebody a while back suggested this:
The intake manifold flows better on this one. Also, the block has reccesess around the bore for better sealing (uses a different head gas
