If you can could you verify something for me, trying to determine which heads are on the 5.0 marine engines like ours vs. what I have been able to research.
Looking to see if you have these 3 bars cast into your heads or not, mine do not.

Also we are able to gain an additional 30-40hp by simply changing the upper and lower intakes to the GT40 style that came on the mid to late 90's Explorers with the 5.0. It is a direct swap on and intakes as a set can be had for less then $300. I am still working on if the ECU can compensate for the added air flow since we do not have oxygen sensors and the ECU runs in open loop. Will have that answer by the end of this week.
I am a gearhead and just can't leave things alone I guess, lol. ie. Plus just happen to be an Engineer for Ford

I will look tonight..
Yes i knew about the Intake. I have been looking at the local LKQ pick n pull lots for one. As for the computer that is the main reason i have not done it yet. also i have been more focused on the interior renovation. as the inteake swap is not hard at all.
I have a 70mm Throttle body on mine and so far i have had no issues in tune. now i also did not notice any gains. but heck it was probably only a couple HP so not blatantly noticeable.. BUT i would love another 30-40.. i will take all that i can get.
I wish that the intake and spark arrestor filter was not butted up to the risers as i would love a better performance air filter that would not be as restrictive as the one i have now.. the only solution i have thought of is to use a 90 at the manifold pointing the TB forward to the bow and this would allow for alternate filter.. i still have to check clearances.
I also have a full Serpinteen assembly that i plan to swap and convert front he V belts.. again have been focused in other areas.
