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 .

Maybe Texas Speed logged the VIN? Call em.

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

Stock and then ported

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.
