Message Hi,

I am currently running ported 40P heads (500 hydro cams, JWT sptings, Ferrea retainders/keepers, Ferrea valve seals, brass valce guides) in my 1991 TT. The engine is coming apart within the next week of so, and I was wondering if the unobtainable 48P heads would be an upgrade to my ported 40P heads or just a waste of my money and time?

Any input is welcome.

Thank you.
AK.
