ok I got the 76cc heads and they were decked tojust enough to make them straight the pistons are the flattop with 4 valve relifs I am sticking with the stock cam iam going to run 4-6psi boost i have a new set of r43ts plugs dont know if they will be good for this application but hope so I have a 750cfm holley doublepump carb thats it . wish me luck

 

If those are the TBI heads with "swirlport" pockets you ABSOLUTELY do not want them!

Remember, 416, 601 or 081 heads ONLY for a good port and polish for 305s.

 

re: the 193's, if you guys will jump over to the TBI forum, you'll see some very impressive post-port work, without removing the vanes...made me do a double take...very comparable (in fact better on the exhaust) than 083's., been a few weeks since I read the thread, but the flow numbers seemed to scream for a single pattern cam...something like 230/190 i/e.

 

Here's the link, more on the exhaust than I thought.
