According to information I have gathered over the years, your 74 heads are pretty much equal to the 95 heads, maybe a little better on the exhaust port.
You will have a compression drop more that likely, specs say the 74 heads are 58cc, the 95 heads are 64, but I've heard of them being as low as 58. I don't think I'd go over 270* duration with 8:1 compression, I've been workin on that one for years too. You don't have enough static compression to work with once your cam starts to lose time under compression. You may gain RPM with that cam, but odds are you won't gain any power. I've pretty much decided to leave mine alone until I rebuild it, damn near any cam I've looked at putting in it would lower my torque, or raise torque and lower my RPM range. If you really intend on swapping the heads, go ahead and buy a set of flat top pistons, even still, by stock specs, you'll only have around 8.6:1 compression with the 95 heads. I have the basic bolt on's, but that's all I'll recommend on this old bird, she just doesn't have enough compression to work with. Good heads tho. :I have a pair of 95 heads off a 5.0. From what i can tell they are referred to as E7TE-6049-AB, anyways i am now in the process of staring at em and wondering what i need to get em running. I mean i know rocker arms and pushrods, but what kind? i want a decent and cheap as possible roller rocker. The cam kit is coming with springs, retainers, locks ect ect. So that said Do i need guide plates? what kind of push rods, and what roller tip rocker will work? oh, and a 1.6 or 1.7 rocker?
