Thumper worked his magic on my GT40s.
Give him a call and let him know what you want out of your set up.
Great guy to chew the fat with.

Good things?...... nope..... Great!...... the following are pics of the GT40p heads I'll be installing in a customer project car, and I can only say that he's a great person to deal with + the quality of his work is superb.

no personal experience... but on other sites as well...nothing but great stuff

i'd send my eddy's to him but i have a pretty awesome head porter down the way

This guy takes countless hours of his life and well-being to sit there and port and work your heads, the way they were meant to be.

All ports are flow matched and every penny spent was worth something to you. The jobs are labor intensive on the wrist, ears and all.

I give him that respect

Keep us up-dated. Take some pics before and after. I would also take measurements just to see what he did with them.
