Jeg\'s/Kaase heads

I know, I know, this has been posted before. Who is running these heads on their 302/5.0 and what are the opinions of these heads?

I havent ssen many people using them yet

Probably has more to do with needing to notch the pistons than lack of interest.[img]/phpBB/images/smiles/icon_frown.gif[/img]

Most guys today want a strictly bolt-on solution. With the placment of the valves on those heads you are going to have to actually measure and modify before they can be installed on a working short block.

I could be wrong?

My understanding of these heads is that they ARE a bolt on set. No piston to valve problems. Heck, they said they even put them on a 100,00 mile 5.0 engine to see what #s they could get. Getting 400 or so hp with the stock cam isn't bad, but the $1,600.00+ price tag could be the real reason people aren't buying.
I am simply curious about real world results. Do they really work as advertised or is it just marketing hype?

They're a straight bolt-on. Because they are a canted valve design you can run stock pistons with somewhat massive lift/duration numbers with out any issues.

Bottom line, money talks. These heads are by no means cheap, and the custom pushrods/valve covers aren't either.

Well I'll agree with you guys. If you say it you don't need to modify the pistons, then I'll not argue the point. I guess the point is that we all have to choose what and who to believe. When we are taking advice online it's not like we can go over to Joe's house and watch or help him put the parts together, so you still have to make a decision,...it's all a crap shoot, unless and until you get your own hands greasy.[img]/phpBB/images/smiles/icon_bow.gif[/img]

I was just going by something I read from a guy, actually a couple of guys....supposedly at least one bought a set of heads, both claim to have spoken to John Kaase and got a similar answers, I guess the point is how much modification was needed .... anyway, he ended up returning them. If you believe what was written.

follow and read the below link to see a similar discussion on the subject, its pretty far down the topic, so I quoted the part I read:

I actually bought a set of them and returned them. Some of the guide machining looked off center and I wasn't finished with the overall quality. I spoke with Jon himself and he said to run the 1.73 ratio rockers. He also said you need a special piston and that getting the pushrod length correct could be a bit tough. I picked up some AFR 205's. Check the flow numbers between the 2 and you'll see what I mean. I would probably run the 225's with your combo. You should make close to 700hp NA. Good luck.

actually...Kaase states "reduced valve notches needed"...hmmm...

I like the "N" heads...they dont even need notches in most applications...

just a bit of port work and you get a very good head...

But that Kaase head shore is schweet...

So, NO ONE here is running these heads or has any firsthand knowledge of them? [img]/phpBB/images/smiles/icon_confused.gif[/img]

Actually, a guy over on Maverick.to was running these heads and after all the issues he ended up selling them. He said that they were by no means a "bolt on deal". After alot of rocker arm alignment and side loading issues he ended up selling them to a guy in Hawaii. He says that he ended up putting ALOT of money into them before he gave up on them. I'll see if I can find that thread.....

Thanks Comet for the info.
