My home inspection of Speedmaster heads
Okay I had them checked out. And they checked out LOL.. he pressure tested them and they were perfect. He looked at the valve job and didn't have a problem with it.. they were at 135 to 145 closed and 320 at my Max lift.. he said they had much more than I will ever go more room for lift.. he said he liked the retainers and the hardend shims... He said he had to clean them up as the lubricant had dried up.. nothing stock of course just the signs of sitting on the shelf for 5 years... he said the valve guides were well within tolerance and the seals again work right. Lubricated everything I put them back together.. $95...
And also compare the Edelbrock gaskets to the cometic and they were identical...
