<br /><br />Good Luck Tony..........<br /><br />Oh,.. BTW,... I ran the #s on your heads at mortec.com,+ they're Standard(light weight) production heads from the dates for your motor........
<br /><br />I already started searching for a pair of heads.....looks like I can get a pair of heads for ~$200, machine shop says ~300 for reconditioning......+ another ~250 to open the valves.......<br /><br />If I go this route I will probably leave the stock valves in.........<br /><br />I also have to buy a manifold!<br /><br />I don't want to beef it up too much where I put the drive in danger either.........<br /><br />From what I have seen the vortec engines are rated @ ~300+ HP......if I opened the valves I would probably be at ~325.....would that be dangerous? remember this is in a 24' Grady.......I would like more power to turn a bigger prop and keep the revs down.......don't intend on running past 3500 RPM's......
<br /><br />Tell me more about the head gasket......do I have to worry about the valve clearance with respect to the piston?<br /><br />I also found a few forums.....gotta regioster to post..........<br /><br />keep in touch!
That's where the Efficiency comes in,........<br />Vortecs with 1.94 valves will flow as good,.. or Better than the heads you have Now,.. With the 2.02 valves.....<br />
Your pistons have the Valve Reliefs,......<br />Shouldn't be any problems,........
<br />The 1st hit is a pretty good paper,+ the guy says to Avoid the 906s I have because the Exhaust Valve Seat is alittle restrictive,.. they came off the Truck engine....<br /><br />Your Pistons shouldn't be any problem at All,......<br />I went back,+ looked,.... You have 4 valve reliefs,+ a small centered dish......<br />Your Not going to be running a Tall Cam,.....<br />I don't see Any Valve to Piston Issues..........<br /><br />You need to find out how Deep your pistons are at TDC,... How far Below the Block Deck.....??<br /><br />Go Google,.....
