Pull a header or intake manifold and check out the ports be the only way

With a scope you could go in though the spark plug hole and maybe look up and see , but that one is not going tell very much of what's been done , going to be very hard to get the scope looped up to see the combination camber

I was going to pull the intake, what should I be looking for ? To see if the cast markings are all grinded down?

I was told they were ported and milled to 68cc by texas speed. but that didn't really make sence to me, I thought 68cc was stock

Should be easy to spot once intake manifold is off , smooth and hogged out intake ports will look very diffrent than untouched head , no casting ruffness and rounded off everything

Whenever I mill a head and most machine shops will stamp the head with the amount removed, for example 030. Porting is obvious with intake or exhaust removed .

The only reason I'm wondering is because I'm about to throw in a night fury cam with 7.4 rods and don't want any issues because of the milling.
I'll try and call them. Thanks |

Or just contact Texas Speed and give them the VIN and see if they've worked on it. Just a thought.

If uncertain I recommend using a pushrod measuring tool to ensure you get the correct length. I have ported and milled heads from GPI. Chamber porting takes material away and milling gets back or close to stock.
