anybody out there have any feedback on the site oldsrocketparts they advertise aluminum heads , are they any good ?

 

They’re repackaged Speedmasters.
I don’t know how well they go thru them but I’ve been told by many the advertised chamber cc’s are seldom correct. Conversely I can tell you first hand the stock valves and valve job are actually ok. However the stock valve springs are total and complete junk. That isn’t an Olds Rocket Parts issue, but unless they replace them you’ll be taking your chances.

 

thanks for the input my problem with my A heads i have are rocker arm is running on outside center on valve stem . nee a shorter pushrod but then rocker will botto out and hit. using rollertp rockers with 3/8 by 3/8 studs and i believe 3/8 pushrods any suggestions on a fix ?

 

How thick are the guide plates and were the heads milled to compensate for that? Sometimes 1/16" thick guide plates will not require milling of the rocker pads. What brand/part number rockers are you using? This information will help to get answers to your problem.
