I have 3 sets of big block heads 1. 3856206. 2. 4081045 3. 346236 so I take it all of them are peanut ports? And 550 sounds great but I cant, definitely in the future ! But if those heads aren't the oval ports I need imight can try and find a set of the 049 or 781s. But if I can't get any I'll take vinnies advice and get the bigger valves and port a set of them.
