Irish Jack,
I took pics of my GT-40p heads to help identify of yours are or are not. I show the bars, straight plug heads and GTP on the corner of each head. I posted it on my page. i did a shit load of research before getting these heads and they outflow the GT-40 heads. They are said to be the best small block heads ford ever made. They straightened the intake and exhaust ports more to give better flow. I believe they also moved the spark plug closer to center for better burn.That's why the plugs are straight. The exhaust ports are shaped a little different and because of the straight plugs a lot of car guys do not mess with them. Their headers or exhaust manifolds will not give enough clearance for those straight plugs and usually leak. I had to re-do my one exhaust gasket because if it is a little off it will leak because of the different shape. Hope this clear up some things!!

Thanks for the info... Those look awesome for $50! I'll look around for a good local marine graphic maker.

the gt-4o head are angle plugs and I am almost certain the p have straight plugs. i will check on my heads tomorrow and let you know!

Hi... Your updated decales look nice!

Did you get them from the dealer? How much does that run? I've been wanting to do something similar to mine... remove the rainbow stripping and add updated decales. Only problem is my base color is white so I can't decide what color decales to add.

I would so recommend it, I surfed more than I boarded last year. It's so super easy behind a SunSport. All you really need is one good sizes sac on the port rear floor. Make everyone sit on the port side. In front is ok but as far back as possible is better. Many people put their surf rope on the tube tow eye.

Awesome! I like seeing some of the similarities and differences. Yours has a lot of small updates or improvements on my 87. Have you surfed behind it yet?

It's kinda like bench racin' you know. Can't get out on the water so this is the next best thing!

I will talk to y'all later... Deadliest catch is on!!!

Need some new pics! Update, update...

Thank you, and happy Easter to you also! Could you please tell me, did you do all the work on your engine or did you take it somwhere? I would love to hit 50mph! My engine is only 240hp, so mid 40mph is tops!
