Putting head back on...need some gasket specs
I'm ordering up gaskets for my front pushrods, rocker housing, cover and head. I have read a ton on here about head gasket choice...measuring squish, compression ratio etc. I get it but I'm not doing anything but reassembly here. The motor is all stock. Gasket choices are vast and lots of opinions. I just want a good average number so I can get back on the road! The old gasket measures between .045 to .047. Seems kinda thick but not sure what they came from the factory with?

Unless you are going to run camshafts, The stock cams may not like the compression bump. Usually one will run a thinner gasket to add small bit of compression. Unless you plan to add camshafts soon I would just stay with a stock replacement thickness. Cometic is always a safe bet either way.

That's basically my question. I can't find a definitive number on stock thickness for the 88. If its in the fsm i wouldn't bother asking. I will be waiting on the cams until next season as I just busted my wallet on the stage 1 setup.

Gaskets are in and before I dig in Im wondering about the carbon build up on cylinder. I can't get all of it off even with several overnight soaks with seafoam. Most of it but not all. Just a decent spot dead center.
Also some of the head gasket material is still lingering. I have some remover from the auto store and a homemade acrylic scraper? These are the first non ironhead heads I've reworked so I don't want to go overboard.

Use a razer blade scraper and shave the gasket material off the head. Be careful not to gouge the metal. You could use sand paper to lightly sand off the carbon on the pistons

Turns out they sent what appears to be the wrong damn gasket kit. Now Im waiting another week before I get to work on it. I'm tempted to go to the dealer and pay up. At least I know they'll give me the proper fitment. Just to check...a 2006 dyna has top hat style valve stem seals?
I wasn't sure that a razor scraper was a god option on critical mating surfaces. It would make it waaay easier.
