Gen IV heads on Gen VI block
I know this has been covered before but indulge me if possible.
Can you put World Products Gen IV Grumpy Jenkins heads on a Gen VI block?
If so are there are pitfalls? What is the best head gasket?
The heads are stock do they more or less power than the Gen VI heads?
Thanks in advance
Steve

Are the Grumpy heads cast iron or alum? I'm not that familiar with their stuff. With either cast iron head and 510-516 ci you could make 575-600hp with some port work, decent size cam and a little more compression than the stock 8.75:1. If they Grumpy heads are aluminum, then with a 510-516 ci you could easily make over 600 hp. Hope this helps.

No reason at all. I use them on a regular basis and love them. However, on the NA engines I stick with the Fel Pro's unless I need a thicker or thinner gasket then .040 to juggle the comp. ratio. On the SC stuff, I won't use anything other than the Cometics. I only use the Fel Pro's to keep the cost down. I take them on an engine to engine basis. If I think it needs a Cometic, I will put it on no matter what the cost. Normally, an NA engine around 600 hp will do just fine with a Fel Pro.
