Cloudmaster,
On www.hotboats.com there is a set of 049's Fresh for $400 + freight. That is a good deal.

the link doesn't work........when you say 049's, what r u referring to, is that a manufacturer? Also, someone suggested labbing my prob. If i was to lab my 25 pitch miragae, would it be toast the first time i hit a rock or something. Can it still be rebuilt?

049 is the last digits of the Chevrolet part number of that head. It is a GM Head. It is very similiar to a Chevrolet 781 head. These are the open chamber large oval port heads. They are a great marine head because the runner sizes are large enough for the volumn of flow you will need but not too large as to lower the velocity of flow like the rectangle port heads. They are good for moderate performace upgrades. If you were going for the maximum amount of flow you would choose the rectangle port heads.

But, make sure they have the 1.88 exhausts and 2.19 intakes and hardened seats for the exhausts or you will be putting a lot more money into them. These heads dont really add much without the bigger valves.

Why couldn't i give my current heads to a good machinist and have them reworked to match the intake or a port and polish or something, then get a mild cam and roller rockers to compliment the head work? Is doing this gonna do anything for me, or make things worse??
