Post some pictures of the ports and valve bowls when you get them torn down.
These as cast, entry level heads should turn out really really good, once ported.
All heads like this improve a lot with porting.
remember the real flow gains are deep in the port. Many people get all carried away makeing the port entry opening big (cause its easy to reach and looks impressive.)
I would use a Felpro 1205 gasket as a guide.
Post some pic after porting too.
I believe these E steet heads are a good buy for guys that like to port their own heads and are on a budget.
Sjop for a valve spring that will do the job for the cam you plan on running
rather than price.
A low price spring that is not up to the task is not a good deal.
You need to measure the present spring installed height and the clearance between the seal and retainer.
Are the spring seats on these heads able to accomodate a larger 1.46" diameter dual spring or just a 1.26" stock diameter spring? The machining to open up the spring pockets for large diameter springs is relatively easy to do.
What cam are you planning to run? Now is the time to get the valvetrain planned and sorted out.
