I have a set of Pro comp heads for sale that are aluminum and COMPLETELY redone last summer, I have paperwork to show also, now out of the box Pro Comps are junk, I spent 1200.00 per set of heads to make right and add Inconel valves, they are good for approx 640 hp, I ahd all the "issues" known on these heads fixed... I need bigger heads to achieve my goals of 700HP so I am selling these.

If you have interest let me know asking 1150 a set, make offer, 440-476-4114

Ok so go with the 500 Efi cam and buy the rollers for the gen 5. Will using the 088 heads with the Pistons listed (30 over) get me to around the 450 mark?

Nobody give this guy any more advice untill he tells us what kind of boat its going in and promises to report back how it runs good bad or ugly lol just kidding but hey it would be nice you know . If you can swing making your gen5 a roller cam that would be a good idea . Or score a mag cam broken in with the lifters numbered to the cam lobe for 75 bucks . Thats ok too . Just make sure the lifter fit in the bores is good and run the correct expensive oilyour gonna get a season out of 8 qts by sounds of it anyway .add your manifolds and a good high rise and carb you should have your 400 horses with some low hour stock 502 or 454 mag heads gen 5 and off the shelf head gaskets borrow a valve spring compressor and leakdown tester take a look before putting it in ..for the life of me cant remember if the hp cams work with pressed in rocker studs of the later heads .you have some springs ? ? ?.must get more sleep .

Hopefully its a fairly light boat with a healthy drive it gonna be peakier than your avg peanut port putter with ls6 heads and a 502 performance cam and the rest of the 450 horse recepe

Yes- 088 heads and the 500 efi cam along with the pistons you are using, is basically an HP 450. The only other things you would need to have a 450 clone is a dart intake and holley 800 carb. If you are not familiar with the 450 it is the 454 version of an HP 500.

Also the heads I have have rocker studs so you can run whatever cam you want.

I also have the timing cover you need and a few other things. If you want to go this route let me know.

He mentioned later heads, thus he's confused. He did say he needs more sleep...LOL.

As we know, later heads he is referring to are stock with threaded bolts, but not adjustable...and adjustable hardware (studs) can be added.
