Just what the title says. .

Bob Madera thats who I use.

Bob is very competitive and he specs them out right for marine use.

Bob Madara hands down .

Currently awaiting a call back from Bob. Thanks guys.

He got me one set a couple months ago and will be calling him for another set soon. No one had them in stock, bob knew someone that had a set they weren't using and had them drop shipped out of Canada to me. Had the heads in less than a week, summit jegs etc all said 6-8 weeks.

Have him get ya a new cam too!

Yes...Cam, lifters and heads

Just ordered 2 sets from Bob last week.
