What heads to use?

[Whitepony98]

On the 01 gt we rebuilt the motor new bearings, rods, manley pistons, but we have two heads to choose from standard or pi the standard heads have been worked bigger valves etc.the pi heads have been ported. witch set should we use? Could we use the standard head with the pi cams or woud there be clearance issues. Neither of these sets of heads are the ones i posted for sale thats still on.

PI heads for sure, the others are boat anchors IMO

PI heads all the way!

Am i wrong in thinking that you can't use non-pi heads without using the non-pi intake as well?

I believe there are adapters out there to make it work, but you are correct that the ports do not match up right.
