I doubt you would be able to tell any difference.
Ok thanks. What else can I do? like a cam? I have a second head that I will be doing 3 way valve job, mild port and polish, bronze valve guides, and hopefully the valves, springs and retainers. So I want to start collecting stuff for it. I found out the head gasket I used is taking a dump on me. Starting to heat up on random. Also putting pressure into my cooling system. Already blew a upper hose a few months ago. I only drive it to and from work until I can fix it. Lucky for me its only 3 miles away.
