Re: acl or fel-pro?

compared to felpro gaskets, ACL suck.

I used a full set of ACl gaskets the first time I put my motor together, they sucked!

Felpro are a good gasket.

ful kit:AFS 8347
intake 2v: 1240

Re: acl or fel-pro?

hello 61sg ,either brand head gaskets will do the job and both are as good as each other unless you decide to use nitrous so in that case use the felpro , the ones with the o ring they are a bit more expensive than the standard felpro head gaskets hope this helps .

I Used Felpro Goes Really Well
Should Just Buy The Full Gasket Kit
Go Felpro For Sure
Just Be Careful Putting Them Together.
Worst Thing Is Letting The Head Drop On The Gasket And Either Denting Or Cracking It.

Re: acl or fel-pro?

I use the Felpro O-ring head gaskets and then use ACL gaskets bought individually for the rest of the motor.

I know of a normal Felpro head gaskets that wept from a cooling passage into a bore. The motor was not used often and rust set in. As it was already at 30 thou, it was the end of the block.

Re: acl or fel-pro?

I would use the felpro steel o-ring head gasket but the rest I think would be very similar .Also the thickness of acl head gasket and felpro are different.
I used felpro kit and ditched the head gaskets in the kit and used the steel o-ring ones from felpro

Re: acl or fel-pro?

I've found Felpro to be very superior to ACL, although I've never compared the head gaskets. The Felpro inlet manifold gaskets are much easier to use. I run mostly Felpro on my engine, no leaks as yet.
