SHOULD I USE Edelbrock Performer RPM Xtreme CNC LT4 Cylinder Heads ON MY 1995 CAMARO?

or should i use a set of trick flow genx heads?SHOULD I USE Edelbrock Performer RPM Xtreme CNC LT4 Cylinder Heads ON MY 1995 CAMARO?
Good swap, but you will need to make sure to use the correct intake for the LT4 also, trick flow are great heads too, and do add a lot of performance, however, you will need to do a little port matching on your lt1 intake if you use those. You can port match machine your lt1 intake to match edelbrock lt4 heads, however that can be problematic, and you should use a flow bench to do it correctly.

Another option is simply to have your existing set of aluminum LT1 heads milled, ported and relieved. Find a shop with a flow bench, and you will be surprised at how much increase in performance you can achieve, have them "port- flow" your intake also, find a higher lift/duration cam with commensurate valvetrain components, and let the good times roll. Unless the edelbrock or trick flow heads are free, you should consider this option. Remember, you already have the stock heads, unless they are trashed, you get more power, and less cost. That is the American way.SHOULD I USE Edelbrock Performer RPM Xtreme CNC LT4 Cylinder Heads ON MY 1995 CAMARO?
If you're going to do this swap, you'll need to swap to the LT4 type intake to get the ports to match up properly. Since that's the case, I'd recommend doing the Edelbrock swap, since they have the intake that's perfectly matched to the heads they make. Otherwise, you'll have some flow disruption (and power loss) from the transition between the two - something you probably don't want!



While you're at it, you'll want to swap out the LT1 cam to either the HOT cam, or the Edelbrock LT4 cam to maximize the flow these heads (and intake) will give you.
