ProComp/Speedmaster aluminum heads

Used them on a set of Eddy heads for two years...running a hughes 230/236 hydraulic cam.....I believe I was using 1.6 rockers...I will have to look in the shop tomorrow...

Now ...you might need to take a look how big a retainer you are using....pretty sure the Eddy are 1.46 spring....

the PRW are shinier and the bushing is a different color then the SM...going to use them again on a stroked 318 i am putting together.....

just ordered a Howards cam for it.....it will be a month or so to get the cam......

I got the SM during one of their Black Friday sales a coupe of years ago...actually got a set of 1.6 and 1.5.....

It is your money so .....just wanted to point out they look very similar....probably prw during days and sm on the grave yard shift...lol
