Hi everyone,
Have aquired a 2nd R5 head off a ph1, am wanting to tune the nuts off it n wondering what are the basic bits to have done, plus mainly who are the people to talk to???
List of tweeks im looking at getting done:
ported n flowed head
matched inlet/exhaust manifold ports
bigger inlet or exhaust valves OR both??
Shortened inlet valve guides
waisted stem on inlet valves (machined so they are thinner for less obstruction)
chemically clean head
reface head/skim
Any help/info much appreciated
